Uninstall npm without using npm - is it possible? - node.js

I was manually updating node and npm. I am using them from Visual Studio only. Typing any npm command e.g.
npm --version
causes the process to hang and CPU consumption goes max. So I cannot uninstall or reinstall npm with npm commands. Node seems to work fine. I am using Node version 6.3.1 and it responds normally to
node --version
Calling
where node
gives only one result.
What I have done so far:
Upgraded Node.js outside VS2015 using command prompt.
Uninstalled Node together with npm from command prompt.
Deleted Node program folder and all subfolders
Uninstalled Visual Studio 2015
Installed VS 2017 RC.
Even after this last step, the behavior of npm is the same - it hangs. Visual Studio refuses to build at all.
I hope my problems will be solved when npm starts to work again. So I figure next to try is to uninstall npm alone followed by a reinstall. How can I do that without using npm?

Use the following process:
Delete %appdata%\npm and %appdata%\npm-cache.
Edit your PATH and remove everything that references npm (to do so, hit "Start" and search for env).
Reinstall Node, then install this tool - and only use this tool to upgrade npm, do not attempt to run npm install npm.

Why is it that npm install doesn't work on my device and I am unable to view the version details even though I've reinstalled?

I'm completely new to using Node and am honestly very confused about how this all works. I have installed node and NPM but every time I try to check the version to see if it's installed, it tells me "command not found". I've been at this for almost 2 hours just deleting all the npm/node files and reinstalling but nothing seems to give. Can someone please explain if there is anything I can do to fix this issue?
-bash: npm: command not found
If I go inside the NPM file through the terminal, it shows me this when I try to run npm install or npm start.
> npm start
npm should be run outside of the Node.js REPL, in your normal shell.
(Press Ctrl+D to exit.)
Add npm to your path (environment variable on windows not sur on linux) if you are using a portable version, if you are using an installed version of node, it should add npm to your path automatically on windows, not sure on linux, npm start will run the start script from your project package.json file. try going into your npm executable folder (generally in node installation folder), n do a ./npm i -g npm

Unable to upgrade to latest version of npm after installing recent Node version [duplicate]

This question's answers are a community effort. Edit existing answers to improve this post. It is not currently accepting new answers or interactions.
I tried this:
sudo npm cache clean -f
sudo npm install -g n
sudo n stable
...but it didn't work.
How do I do this on Windows?
Note: The question is specifically asking how to upgrade npm, not Node.js. If you want to update Node.js over a CLI on windows, I recommend running winget upgrade -q NodeJS or use chocolatey for that.
What method should I choose to update NPM?
Node.js v16 or higher?
npm install -g npm
Node.js v14 or below?
Consider updating to latest LTS release of Node.js
npm-windows-upgrade
Upgrade with npm-windows-upgrade
Run PowerShell as Administrator
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install -g npm-windows-upgrade
npm-windows-upgrade
Note: if you run the Node.js installer, it will replace the Node.js version.
Upgrades npm in-place, where Node.js installed it.
Does not modify the default path.
Does not change the default global package location.
Allows easy upgrades and downgrades and to install a specific version.
A list of versions matched between NPM and Node.js (https://nodejs.org/en/download/releases/) - but you will need to download the Node.js installer and run that to update Node.js (https://nodejs.org/en/)
Upgrade with npm
npm install -g npm
Note: some users still report issues updating npm with npm, but I haven't had that experience with v16+.
Download and run the latest MSI. The MSI will update your installed node and npm.
To update NPM, this worked for me:
Navigate in your shell to your node installation directory, eg C:\Program Files (x86)\nodejs
run npm install npm (no -g option)
Like some people, I needed to combine multiple answers, and I also needed to set a proxy.
This should work for anyone. I have zero desire to run an EXE file or MSI file .. uninstall/ reinstall, or manually delete files and folders. That is so 1999 :P
Run this to update NPM:
Run PowerShell as administrator
npm i -g npm // This works
I am not thinking this code actually upgrades your npm version below
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install -g npm-windows-upgrade
npm-windows-upgrade
(courtesy of "Robert" answer)
Run this to update Node.js:
wget https://nodejs.org/download/release/latest/win-x64/node.exe -OutFile 'C:\Program Files (x86)\nodejs\node.exe' (courtesy of BrunoLM answer)
If you get `wget : Could not find a part of the path .... "**, see below ...scroll down. Reading Web Response... It's at least punching through the firewall /proxy (if you have one or have already ran the code get through ...
Otherwise
You might need to set your proxy
npm config set proxy "http://proxy.yourcorp.com:811" (yes, use quotes)
2 possible errors
It cannot find path of the path solution "where.exe node" (courtesy of Lonnie Best Answer)
E.g. if Node.js is NOT living in "Program Files (x86)" perhaps with where.exe, it is living in 'C:\Program Files\nodejs\node.exe'.
wget https://nodejs.org/download/release/latest/win-x64/node.exe -OutFile 'C:\Program Files\nodejs\node.exe'
Now perhaps it tries to upgrade but you get another error, "node.exe is being used by another process."
Close /shutdown other consoles .. command prompts and PowerShell windows, etc. Even if you're using npm in a command prompt, close it.
npm -v (3.10.8)
node -v ( v6.6.0)
DONE. I'm at the version that I want.
You can update your npm to the latest stable version with the following command:
npm install npm#latest -g
Use PowerShell to run it. This command doesn't need windows administrator privileges and you can verify the result with npm -v
You can use Chocolatey which is a package manager for windows (like apt-get for Debian Linux).
Install fresh (you might need to uninstall previously installed versions)
> choco install nodejs
Update to the latest version
> choco update nodejs
and for npm
> choco update npm
The previous answers will work installing a new version of Node.js (probably the best option), but if you have a dependency on a specific Node.js version then the following will work: "npm install npm -g". Verify by running npm -v before and after the command.
This works fine for me to update npm on Windows 7 x64:
Windows start
All Programs
Node.js
Node.js command prompt (alternative click)
Run as administrator
$ npm -g install npm
remove C:\Program Files\nodejs\npm.cmd the new npm will be at C:\Users\username\appdata\roaming\npm\npm.cmd
Hope this helps.
Open PowerShell as administrator.
To install a first time you can use this small script to download the latest msi and run it
$nodeLatest=((curl https://nodejs.org/download/release/latest/).Content | findstr x64.msi) -replace "<(.*?)>", "" -replace "\s+.+", "";
wget "https://nodejs.org/download/release/latest/$nodeLatest" -OutFile (join-path $env:TEMP node.msi); Start-Process (join-path $env:TEMP node.msi)
On future upgrades you can download just node.exe and update npm with
wget https://nodejs.org/download/release/latest/win-x64/node.exe -OutFile 'C:\Program Files\nodejs\node.exe'
npm i -g npm
You should now have the latest node and npm.
I went a little further and decided to implement a nvm for Windows.
https://github.com/brunolm/nvm
Install-Module -Name power-nvm
nvm install latest
nvm default latest
1. Installing latest npm version
npm install –g npm#latest
(You can type "npm –version" to check that)
2. Installing Node
a. Install node new version via following URL: https://nodejs.org/en/download/current/
Follow the default choices
b. Remove C:\Users\\AppData\Roaming\NPM
c. Remove C:\Users\\AppData\Roaming\npm-cache
Optionally:
d. (Delete node_modules folder in your current project folder)
e. npm cache verify
f. npm install
Use Upgrade npm on Windows
This is the official document for a user to upgrade npm on Windows!
Here is my screenshot!
For what it's worth, I had to combine several answers...
Uninstall Node.js in control panel Add/remove programs.
Delete directories, both C:\Program Files (x86)\nodejs\ and C:\Program Files\nodejs\ if they exist.
Install the latest version, http://nodejs.org/download/
How to Update Node.js:
Uninstall Node.js. Click the Start menu, type "Change or Remove a Program", click on the item shown, find Node.js in the list and uninstall it.
Delete directories, both C:\Program Files (x86)\nodejs\ and C:\Program Files\nodejs\ if they exist.
Install the latest, https://nodejs.org/en/download
The uninstall/delete/install seems unnecessary, but it often is and this will save your time.
These instructions come from Microsoft.
How to Update NPM:
https://www.npmjs.com/package/npm-windows-upgrade
This is the official documentation for upgrading npm on windows.
All was tested and working on Windows 10 (2017).
this is best tool to maintain version of NODE.Js i NVM
Node Version Manager (nvm) for Windows
but for Windows, with an installer. Download Now! This has always been a node version manager, not an io.js manager, so there is no back-support for io.js. However, node 4+ is supported.
For me, after totally uninstalling node 10.29, and then installing node 4.2.2, there remained a 10.29 node.exe file in my c:\windows folder.
I found this by using the following command:
where.exe node
The command returned:
C:\Windows\node.exe
C:\Program Files\nodejs\node.exe
So even though I had successfully installed version 4.2.2 via the msi executable, the command node -v would continue to report I was running version 10.29.
I resolved the problem by deleting this file:
C:\Windows\node.exe
Thereafter, node -v reported the upgraded version instead of the unwanted remnants of the prior version.
For NodeJS
Download required node version msi from here and install
for Npm
Run PowerShell as Administrator
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install -g npm-windows-upgrade
npm-windows-upgrade
This works fine for me
Run Command Prompt as Administrator
Navigate to the folder containing nodejs (eg. C:\Program Files\nodejs)
Run Powershell -ExecutionPolicy Unrestricted
Run npm-windows-upgrade
This will show list of versions available to install. Just select your desired version by moving up/down key & Press Enter.
This'll update your npm
To check the current version of npm
Run npm --version
Command Prompt Screenshot
I was also facing similar issues. I followed below mentioned steps and it worked for me:
go to Windows > Start > Node.js
right click on Node.js command prompt
click on Run as administrator
ping registry.npmjs.org
npm view npm version
cd %ProgramFiles%\nodejs
npm install npm#latest
and npm updated successfully. Earlier I was trying for CMD and that was throwing error. may be some path issue that got resolved by running NodeJs Command Prompt. hope it'll work for you. try this.
OK guys, I read (tried on Windows) all the previous stuff and all of these answers have their own disadvantages.
For the best way to update Node.js (at least for me), go to https://nodejs.org/en/
Then download the last version and install it in same folder you installed the previous version in - 1 min and it's done. You don't need to remove any old files.
Then update npm typing in cmd: npm install --save latest-version
To install the updates, just download the installer from the Nodejs.org site and run it again. The new version of Node.js and NPM will replace the older versions.
The easiest way I found so far to update Node.js is using Chocolatey.
Use Chocolatey to install or update the latest version of Node.js on Windows:
Step 1: First, ensure that you already have Chocolatey installed. If not, use an administrative shell to install chocolatey through cmd.exe or PowerShell.exe. For more information, visit: https://chocolatey.org/docs/installation
Step 2: Install with cmd.exe. Run the following command:
#"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"
To install with PowerShell.exe, visit: https://chocolatey.org/docs/installation
Step 3: Install or Update with following commands on cmd.exe (on administrative mode)
To Install Node.js: cinst nodejs.install
To Update Node.js: cup nodejs.install
follow these steps for window 10 or window 8
press WIN + R and type cmd and enter
npm i -g npm#next
npm i -g npm#next OR npm i -g node#{version}
Remove environment path C:\Program Files\nodejs from envrionment variable PATH.
type refreshenv in cmd
Now you will have your new version which you installed.
Note: If you don't remove path. You will see the previous version of node.
PowerShell does not execute npm directly, so I suggest using
.\npm install -g npm-windows-upgrade
.\npm-windows-upgrade
And it failed with:
You wanted to install npm 6.1.0, but the installed version is 3.10.10.
A common reason is an attempted "npm install npm" or "npm upgrade npm". As of today, the only solution is to completely uninstall and then reinstall Node.js. For a small tutorial, please see http://aka.ms/fix-npm-upgrade (dead link).
Please consider reporting your trouble to npm-windows-upgrade.
I followed josh3737 and installed the latest MSI from the Node.js homepage.
But I had the additional problem that I still had the old version of Node.js and npm on the command line. The problem was caused by the new installation, and that it was installed into
C:\Program Files (x86)\nodejs\
instead of the previous installation in
C:\Program Files\nodejs\
The new installation added the new directory into my path variable after the old one. So the old installation was still the active one in the path. After removing C:\Program Files\nodejs\ from system path and C:\Users\...\AppData\Roaming\npm from user path and restarting the command line the new installation was active.
Maybe the least path was a local problem that has nothing to do with the new installation. I had two links to AppData\Roaming\npm in it. And maybe this can also be fixed by first uninstalling Node.js and installing the new version afterwards.
You can use these commands:
npm cache clean
npm update -g [package....]
If you are upgrading from a previous version of node, then you will want to update all existing global packages.
You can also specify the package name to be updated.
This might help someone. Neither "npm-windows-upgrade" nor the installer alone did it for me. Powershell was still using an older version of node and npm.
So this is what I did (worked for me):
1. Download the latest installer from nodejs.org. Install node. It will update your node; everywhere (Powershell, cmd etc.).
2. Install the npm-windows-upgrade package (npm install -g npm-windows-upgrade) and run npm-windows-upgrade.
I didn't uninstall anything and didn't set any paths.
In my case, I discovered that I had two copies of Node.js installed. One under "C:\Program Files\nodejs" and another under "C:\Program Files (x86)\nodejs".
This is what worked for me.
Open a local folder other than the one in which nodejs is installed.
Install npm in that folder with command npm install npm
Navigate to the folder containing node js. (C:\Program Files\nodejs\node_modules)
Delete the npm folder and replace it with the npm and bin folders in the local folder.
Run npm -v. Now you would get updated version for npm.
Note: I tried installing npm directly in "C:\Program Files\nodejs\node_modules" but it created errors.
Start
Search for windows powershell
Right click and run as administrator
Type: where.exe node (returns the path of node.exe in your system. Copy this)
wget https://nodejs.org/download/release/latest/win-x64/node.exe -OutFile 'PATH-OF-NODE.EXE_WHICH_YOU_COPIED_JUST_NOW'
To check if it has worked, go to your Git bash/Normal command prompt and type: node -v
Here you can find the current version of node: https://nodejs.org/en/blog/release/

Npm isn't getting automatically installed on installing node.js

While hosting my webapp on heroku I got a message of some bugs in my npm package, my npm package was of version 3 and node.js was of version 8, I wrote thinking that I can update my npm version I tried to update it but the version remained same so I decided to uninstall it and wrote the command "npm uninstall " and than again tried to install npm but in vain ,finally I uninstalled my node.js and reinstalled tha npm will automatically get installed with it, but this too didn't work now I have node of version 10 with no npm which I got to know by checking version of npm which gave me message of "command not found ", now my every try to install npm has failed , may anyone suggest me what I can do to restore my losses and resume my work.
I am not sure if you have Linux or Windows. First I would check if the npm folder is in path.
You can follow one of these two to add to path if it is not done yet.
Windows
Linux
Alternatively you can install node with node version manager (nvm):
nvm linux and mac
nvm windows

Node Sass couldn't find a binding for your current environment

I am having issues building an app because node-sass keeps failing with the error.
ERROR in Missing binding /Users/warren/Sites/random-docs/my-cms/node_modules/node-sass/vendor/darwin-x64-11/binding.node
Node Sass could not find a binding for your current environment: OS X 64-bit with Node 0.10.x
I have tried running
npm rebuild node-sass
which says
Binary is fine; exiting.
When running node -v I get v6.2.2
Which is different to what the sass error says "Node 0.10.x". I can't figure out why it is getting the wrong version. I have also tried removing the node_modules folder and running npm update or npm install, both of which did not resolve the issue. Any ideas?
I had the same problem
There is an error in your gulpfile:
Error: Missing binding E:\allapp\badshaindiancuisine\node_module\node-sass\vendor\win32-x64-46\binding.node
Node Sass could not find a binding for your current environment:Windows 64-bit with Node.js 4.x
Found bindings for the following environment:
    - OS X 64-bit with Node.js 4.x
How to solve the problem
By going into the project folder and then executing the command:
npm rebuild node-sass
For those that are using Visual Studio:
Currently working for VS 2015, 2017, 2019, 2022 (via below and/or replies from this post)
Task Runner Explorer can't load tasks
For VS 2015
Go to: Tools > Options > Projects and Solutions > External Web Tools
For VS 2017(.3), VS 2019, and VS 2022
Tools > Options > Projects and Solutions > Web Package Management > External Web Tools (per #nothrow)
In VS 2017, 2019, 2022, you also need to put $(PATH) above $(VSINSTALLERDIR)\Web\External
Reorder so that $(PATH) is above $(DevEnvDir)\Extensions\Microsoft\Web Tools\External
Deleting node_modules and running npm install and then npm rebuild node-sass did nothing.
**Just execute: ** npm rebuild node-sass --force
If the above for some reason didn't work out for you, try this:
Delete node-sass folder under node_modules
npm install
In my case it also couldn't find Python.
Following procedure solved the issue (Windows):
npm rebuild node-sass --force
-- cannot find python.exe, if you have Python installed, add it to your path:
set PYTHON=C:\Python27\Python.exe
-- else: download python "Windows x86-64-MSI" installer from https://www.python.org/downloads/release/python-2714/
-- install python
-- at installation start check: add env variable to path
-- after successfull installation:
npm rebuild node-sass --force
-- finished successfully
Worked for me:
Just delete the node-sass folder and run npm install.
I had the same problem in a Windows environment, receiving the following error:
Error: Missing binding C:\Development{ProjectName}\node_modules\node-sass\vendor\win32-ia32-47\binding.node
Node Sass could not find a binding for your current environment: Windows 32-bit with Node.js 5.x
Found bindings for the following environments:
   - Windows 64-bit with Node.js 6.x
None of the npm commands listed in the other answers here (npm install, npm rebuild node-sass, etc.) worked.
Instead, I had to download the missing binding and place it in the appropriate destination folder.
The bindings can be found on git. Match the file with the folder name identified after /node_modules/node-sass/vendor/ in your error message ('darwin-x64-11' in your case, so you'd want the darwin-x64-11_binding.node file).
Create the missing folder in your project (/node_modules/node-sass/vendor/darwin-x64-11), copy the .node file to the new directory, and rename it to binding.node.
Node-sass release URL:
https://github.com/sass/node-sass/releases
I had a similar problem and the reason was that there were two versions of Node installed in my machine: one "global" and another one at the project level.
Sass will build correctly only if the Gulp build is running under Node.js 4.x version, so make sure you upgrade the version of Node you are using.
PS: If you completely remove the node_modules folder in your project and re-build from scratch, npm will download the correct dependencies for your current system & node version.
npm rebuild node-sass --force
Or, if you are using node-sass within a container:
docker exec <container-id> npm rebuild node-sass --force
This error occurs when node-sass does not have the correct binding for the current operating system.
If you use Docker, this error usually happens when you add node_modules directly to the container filesystem in your Dockerfile (or mount them using a Docker volume).
The container architecture is probably different than your current operating system. For example, I installed node-sass on macOS but my container runs Ubuntu.
If you force node-sass to rebuild from within the container, node-sass will download the correct bindings for the container operating system.
See my repro case to learn more.
in some cases you need to uninstall and install node-sass library. Try:
npm uninstall --save node-sass
and
npm install --save node-sass
look at this its work for me,
Stack link here
node-sass node module uses darwin binary file which is dependent on the version of node. This issue occurs when the binary file is not downloaded or wrong binary file is downloaded.
[![Node sass error][1]][1]
Reinstall node modules will download expected binary of node-sass:-
For Mac users:
rm -rf node_modules
npm cache clean --force
npm i
npm rebuild node-sass --force
For Windows users:
rmdir node_modules
npm cache clean --force
npm i
npm rebuild node-sass --force
but for some users, you need to check your node version's compatibility with node-sass version. Make it compatible using below table and run above commands again to fix this issue.
This is node compatibility table with node-sass

* Docker related answer here *
Answer for if you are seeing this problem, or something similar, and are using Docker.
Cause: When copying over the current file structure to inside the Docker container, you may be copying over node modules from one OS system to another (e.g. a Mac to Linux container).
Solution:
Add a .dockerignore, and inside add:
node_modules
This will cause an npm install to install the bindings for the docker environment, rather than your local machine environment.
If your terminal/command prompt says:
Node Sass could not find a binding
for your current environment:
OS X 64-bit with Node 0.10.x
and you have tried the following commands such as:
npm cache clean --force
rm -rf node_modules
npm install
npm rebuild node-sass
& still NOTHING works..
Just run this in the terminal manually: node node_modules/node-sass/scripts/install.js
now run npm start or yarn start
Try to add suffix --force
npm rebuild node-sass --force
For my particular case none of the above answers worked. So what it worked:
rm -rf node_modules
rm -rf /tmp/*
rm -rf /root/.npm/node-sass
npm uninstall --save node-sass
npm cache clean --force
npm cache verify to check that nothing is left in the cache
npm install
Altough I haven't tried to reproduce the sequence it was a combination of the above that worked.
In addition you may also try:
npm install --save node-sass or npm install node-sass -g
npm rebuild node-sass
npm install bindings
I had the same problem
throw new Error(errors.missingBinary());
^
Error: Missing binding /path/to/project/node_modules/node-sass/vendor/linux-x64-47/binding.node

That was because I did npm install using a different nodejs version,
try deleting node_modules folder installing and starting
cd your_project
rm -rf node_modules
npm install
npm start or gulp or whatever
If you are using nvm do
nvm use stable // or your favorite version

I had the same problem with Node v7.4.0 Current (Latest Features).
Did some reading here and downgraded Node to v6.9.4 LTS and after running npm rebuild node-sass it downloaded the binary and everything started working.
Downloading binary from https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-48_binding.node
Download complete .] - :
Binary saved to D:\xxx\xxx-xxx\node_modules\node-sass\vendor\win32-x64-48\binding.node
Caching binary to C:\Users\user\AppData\Roaming\npm-cache\node-sass\3.13.1\win32-x64-48_binding.node`
I'm a Windows 8 user, recently updated Node to v8.11.1 and npm to v6.0.0 and faced similar issue. Nothing worked - npm install -g node-sass#latest or deleting the node-sass directory from the project node_modules/ - none of 'em worked for me.
The Laravel Mix was throwing an error to my browser console saying a missing node: win32-x64-57. I don't know whether it's because a slower internet connection or something, the node was missing during the update.
Hence some of the answers directed me to look at the Node-Sass releases, and I found the solution.
Step 1: Check your node-sass version using the command: npm view node-sass version (the {your version} in step 4)
Step 2: Get to Node-Sass Releases
Step 3: Get your release and find the missing node in the assets listed under every release, and download the file
Step 4: Get to your PC's C:\Users\{User}\AppData\Roaming\npm-cache\node-sass\{your version}\ and put the downloaded .node file inside the version folder
And you are done.
In my case the node-sass version was 4.9.0 and the missing node was win32-x64-57_binding.node, so I downloaded the .node file from 4.9.0 release and followed step 4.
For Visual Studio 2015/2017, Right Click on your package.json and Click on Restore Packages.
This will make sure that the npm from the Visual Studio Tools External Tools is run and the binding will be rebuild based on that.
I had the same issue. I couldn't find any proper working solution in here, so I found mine:
Inspired by #Rob-Scott solution and other pointing that we could have 2 versions of Node.js installed, I went to C:\Program Files (x86)\nodejs and realized that I had a node.js version installed in addition to the VS default installation.
My solution was quite simple:
Go to Tools > Options > Projects & solutions > Web package management > External web tools
Click on add an entry (most left of the top-right block of buttons)
Enter C:\Program Files (x86)\nodejs, validate by pressing enter
Bring it at the top of the list
Enjoy
Probably Node.js is not set well in the PATH variable, but this is my working very quick solution, my 2 cents :)
This happens when in your workstation you run an update of Node.js and you are using node-sass globally.
So you should uninstall node-sass globally
npm uninstall -g node-sass
And then you have to install it globally, again
npm install -g node-sass
The post dependencies for node-sass is not getting installed without the package.json inside node-sass
Running it manually solved for me
node node_modules/node-sass/scripts/install.js
credit: link
Run the following commands, it works fine for me.
npm install node-sass -g
npm rebuild node-sass
nvm use 10.16.3
node node_modules/node-sass/scripts/install.js
ng serve --poll=2000
This worked for me:
yarn add --force node-sass#4.14.1 or yarn add --force node-sass
This usually happens because the environment has changed since running npm install.
Running npm rebuild node-sass builds the binding for the current environment.
Create a new directory in node_modules/node-sass/vendor/linux-x64-46/ .
the download fil from https://github.com/sass/node-sass/releases
(linux-x64-59_binding.node) based upon your version.
paste it in node_modules/node-sass/vendor/linux-x64-46/ rename it to binding.node
I had this issue when upgrading from VS 2017 Professional to Enterprise
Close VS
Delete node_modules
Open VS
Right click package.json and select 'restore packages'
Delete node_modules folder.
Install dependencies again. (npm i)
None of the install/rebuild solutions resolved the issue for me (using gulp).
Here is how I resolved it:
1) Download the missing binding file from the repository.
2) Rename the file binding.node.
3) Create node_modules/node-sass/vendor/darwin-x64-11 (path from error message) directory if it doesn't exist.
4) Add the binding file to node_modules/node-sass/vendor/darwin-x64-11
Just refresh your npm cache and:
npm cache clean --force
npm install
It always works for me in the same case.
UPD: Your problem may also be by reason of absence of a global sasslib.
npm install -g sass
Open Visual Studio 2017
Go to Tools -> Options…
Go to Projects and Solutions -> Web Package Management
Move $(PATH) to the top of that list and close that window.
Restart Visual Studio.
This worked in my case, because my node version is 11.x
Probably you have a build with different node version than the current one. Try running these commands and it should fix the issue.
npm cache clean --force &&
rm -rf node_modules &&
rm -rf package-lock.json &&
npm i

Node.js error : failed to initialize context

I just installed Node.js from Visual Studio installation.
When I tried to call node on the command prompt, I got this error. I also got this when I tried to do npm init and npm install
How do I fix this?
I encountered this problem on my Windows 10 64-bit computer. From looking at Programs and Features, I saw that I had Node.js and Node.js Chakra installed. I uninstalled Node.js and then downloaded and installed again it from https://nodejs.org/en/download/.
This, however, did not fix the problem. So I uninstalled Node.js Chakra; and when I opened a new command prompt, node and npm were working.
However, I'm not sure if I needed to uninstall and reinstall Node.js or if I only needed to uninstall Chakra. I probably should have uninstalled Chakra first and node and npm might have worked after that.
