I updated to the latest node v9.1.0 and now npm doesn't work.
npm WARN npm npm does not support Node.js v9.1.0
It turns out that the current installed npm is not compatible with the new node and has a hard time updating.
The solution is to uninstall npm and then reinstall node which will contain the correct version of npm.
Here's how:
Uninstall npm.
Mac:
sudo npm uninstall -g npm
Windows:
npm uninstall -g npm
Install node from https://nodejs.org
Uninstall the global instance of npm:
npm uninstall -g npm
This will cause your system to fall back on the version of npm installed by node 9.1.0 and the warning will disappear.
What worked for me was to delete npm and npm cache from C:\Users\chrisd\AppData\Roaming
Then I ran npm i -g npm#next for the latest version of npm for Node 9.x
NPMJS.org has issued a new release 11.27.2017 -- npm v5.6.0
(You may not have to delete the npm/npm cacheif you just upgrade, but I had already done that before finding the new release)
NPMJS Release notes
Fixed my issue update to 5.71
npm uninstall -g npm
npm i -g npm#next
Had similar issue in linux/ubuntu, below helped solving it.
Remove existing versions of npm and node:
sudo apt --auto-remove purge npm
sudo apt --auto-remove purge nodejs
Re-install node
for me worked
npm uninstall -g npm
npm i -g npm#next
No need for manual installation or clearing the cache.
Run with admin credentials if needed.
I saw this warning after I upgraded to Node 10.4.1 after that I just ran npm uninstall -g npm with -g flag to remove it globally and the error was gone. I guess it updated my npm to version 6.1.0
Solution :
Go to the path where you can find the debug log (this file is found in your npm-cache folder) C:\Users\yourname\AppData\Roaming
Delete the NPM and NPM-Cache folder, but DO NOT reinstall node. Once deleted go back to your command line and re-use the command " npm install -g npm#latest "
What worked for me - On Ubuntu
Install nodejs
sudo apt install nodejs
Install npm
curl -L https://www.npmjs.com/install.sh | sudo sh
If you are unable to uninstall npm, instead you can skip that step and just
Reinstall npm https://nodejs.org/en/
This error occurs when the npm version not compatible with the node version. However npm uninstall -g npm also gives the same error for me.
So following steps work for me.
Option 1:
Step1: Follow this directory
C:\Users(your username)\AppData\Roaming
Step2: Delete the npm folder. And if there is a folder called `npm cache, delete it also.
Step3: Run npm clean cache —force ( — force is now required to clean cache)
If the above option is not worked for you please follow the below steps.
Option 2:
Follow this directory
C:\Users(your username)\AppData\Roaming
Delete the npm folder and if there is one mom cache folder.
Run npm clean cache --force ( -- force is now required to clean cache)
Make sure everything to do with Nodejs is deleted and uninstalled.
Reinstall Nodejs.
I had the same issue with npm when I have updated Node js on windows. I tried many things but only working solution was :
First uninstall npm with below command
npm uninstall -g npm
Now Install latest version
npm install npm#latest -g
If you are using Mac and brew, that's how I've got rid of this problem:
Even though I installed and reinstalled node with brew, with last version 11.8.0, apparently it kept using the last version
fdecollibus$ npm install --global gatsby-cli

+ gatsby-cli#2.4.8
npm -v gave me back version 5.6.0. I've therefore noticed that /usr/local/lib/node_modules had wrong permissions assigned to root:wheel.
A chown did not fix the problem: I've had to manually delete the content of the folder (cd /usr/local/lib/node_modules and -careful - type rm -rf * ) to get rid of the folder.
Then I've run brew uninstall node and again brew install node, and finally npm -v gave me back 6.5.0
Executing npm uninstall -g npm gave me same error
Uninstall Node.js installed in the system
Goto c:\Program File\nodejs (default location of the nodejs installation). Remove all contents of the folder manually.
Remove npm, npm-cache folder from Roaming folder under your username.
Install Node.js again.
running npm install #angular/cli -g worked for me.
I was getting the below warning when I executed, npm install to install package.json for my angular project.

According to #Ilyich, I uninstalled global npm, npm uninstall -g npm
And then I executed npm install to install my package, it installed successfully.
Navigate to the Appdata by typing %AppData% in the run or search.
Delete the npm and npm-cache folder and then install the nodejs again. It solved the issue for me.
If you are getting the same warnings while creating or importing an Angular project in an IDE such as Eclipse ,do the following:
File->New->Angular
In the window that appears change the versions of Nodejs and NPM to "use system installation"
...
If the process crashes at "installing packages for tooling via npm"
Close the terminal in IDE and manually go to the project directory and do "npm install".
Refresh the project in IDE
I had a similar issue trying to install other stuffs.
And looks like the npm version was not compatible with my node version.
In my case i had npm 5.4.2 and node v10.15.0
At the end of this process i had the version npm 6.7.0 and node v10.5.0
First Option:
I downgrade the version of node and other tools.
On terminal execute the next command with the version to be installed. (Example if we need change to node 8.14.1)
1.- Npm install -g node#8.14.1
Then we execute the command to uninstall the version to be removed.
2.- Npm uninstall -g node#8.15.0
After that we need execute the next command to set the new path
3.- Npm update -g node#8.14.1
Finally we only need execute the version to see if the changes were added successfully
4.- Node -v
In this case we will see the version as 8.14.1 and we finished the process.
If you want do it for Appium and Npm version you can open a new terminal and follow the same steps in order to change the version. For example:
Npm install -g appium#1.7.2
Npm uninstall -g appium#1.10.0
Npm update -g appium#1.7.2
Appium -v
In my case you must have the next versions:
Node 8.14.1
Npm 6.4.1
Other Way:
To solve it i just execute in the terminal the next line.
curl -L https://npmjs.org/install.sh | sh
After download a few files (took around of 10 minutes to see results in the terminal) i was able to continue working with the new latest and compatible version of both tools.
The next WARM was displayed in this case.

I am on a macOS and what ended up working for me was uninstalling npm, relinking Node, and reinstalling Node through Homebrew. (Prereqs: Have Homebrew installed and have a very confusing setup where npm and Node don't work together)
1. To uninstall homebrew:
If you are on a Mac, you probably don't see the AppData\Roamingfolder; you should instead go to npm root -g and delete the npm_modules folder. Now, when you type npm --version your computer should be confused.
2. Reinstalling node:
Try doing brew install node and if you already have node installed, your computer will ask you to reinstall it. If you do brew reinstall node and your versions of brew and npm look good, then you don't need to do the last step!
3. If you need to link the correct version of Node:
This step was something I think was my fault since I think I had installed Node through Homebrew as well as the actual online download. Follow the suggestions after brew link node which should take you to brew link --overwrite node. There will be around 7 directories that the command will not be able to overwrite, which you should all delete using sudo rm -rf directory_name. (Do use your common sense, don't delete something important.) After you are finally able to run the brew link --overwrite node command without any errors, you should then do brew reinstall node since you don't have npm anymore.
Tada! You hopefully now have version of npm and node that hopefully can work together.
Just install latest version of Node.js from https://nodejs.org
This will automatically update npm for you
Easiest way I found was to install the latest node with brew and the latest npm manually:
brew uninstall node
brew install node
npm install -g npm#latest
This removed the warning message. For some reason brew wasn't linking the new npm installed by node while it was updating node itself.
The easiest way(for windows) is to use the installer to remove node, then use it to reinstall node, at which time it will install the correct version of npm. running the above uninstall commands does not work, since the wrong version of node is installed, otherwise you wouldn't have this issue.
You can uninstall node current version, and install a early version that support npm. Then run npm install npm#latest -g and install current node version.
It's work for me
lowering the npm version worked for me (windows 10):
npm i npm#6.14.11
To upgrade the npm and Node:
Step 1. Uninstall the npm:
Mac: `sudo npm uninstall -g npm`
Windows: `npm uninstall -g npm`
Step 2: Install the latest version of Node: https://nodejs.org/en/
I am using the version of node that is stated on electron's site, which is 7.4.0 and I'm using NPM version 4.0.5 (Windows).
The problem I'm having is with the npm install command in the cloned electron-quick-start folder. I have tried using the command with --save-devand -g but they don't do anything to help.
Upon using just npm install;
fetchMetadeta: still install loadAllDepsIntoIdealTree
With the above stated arguments (output);
--electron-quick-start#1.0.0
Then npm start after the above output;
Pastebin
Any help would be greatly appreciated, thanks.
You must get npm install to work before you can start the app
You could try the following
npm cache clean
npm install This will cache clean of npm
npm install -g yarn
yarn install This will install yarn (This will probably work but it might not be what you're looking for). Yarn is an alternative to npm
npm -g install npm
npm install This will reinstall npm
And I would look into nvm and nvm-windows
And if none of those work I would look at
this issuse on github
And if that doesn't work I would just look at google
I am trying to install with this command "npm install -g #angular/cli".
But I always get the error "Error: not found: python2"
Is there something I am missing here?
Just in case you do not want to downgrade, which is not needed anyways.
Then this is what you should do,
Fix node-sass version issue first:
The issue is with the version of node-sass (prior to the python2 error). So install it as
npm install node-sass.
Now run npm install
If it asks to fix using npm audit fix. Go ahead!
Downgrade to npm version 4, try this:
npm install -g npm#4.6.1
I had the same issue. I manage to install the python 2 version. It got solved this is the version i installed
https://www.python.org/ftp/python/2.7.15/python-2.7.15.amd64.msi
I had install Node.js 4.2.2
i am trying to install socket.io package using npm install socket.io
but the npm installer just keep running with no error output in console after 30min..
Try to install some another package, mongoose for example. If it also fails try to reinstall npm by
npm install -g npm
Try the following:
npm install -g npm
npm cache clean
npm install socket.io
Also check if you permission to create node_modules folder in the directory you run npm.
You can downgrade your nodejs to v.4.2.1 for example, don't forget to clean npm cache after that, and then run npm install command.
First try to remove these packages and then install. Like
npm remove socket.io
Then
npm install socket.io
may be the incomplete installed files are blocking it to install properly
You need to update your npm anyway.
Try from link install:
curl -L https://www.npmjs.com/install.sh | sh
Or you can compile it with make if you clone sources from github
I want to use the node-sass module in my node.js v0.12 application to benefit from the performance of libsass.
I executed npm i node-sass to install the module, no errors so far.
Now the mess starts:
If I just open the REPL in a terminal to try out node-sass then everything works fine but if I include it in my project files and run node myfile.js then I get the following error message:
Error: `libsass` bindings not found. Try reinstalling `node-sass`?
The module's description at npmjs.com states that there might be a problem with resolving #!/usr/bin/env node under Ubuntu and how to fix this but that is not the case on my machine.
I could not find anything useful so I hope that you might help me.
I'm using node v0.12.2 under Ubuntu 14.10.
P.S.: I already tried to reinstall node-sass but without success. Nothing changes.
If you're using node 4.x or later then you need to reinstall gulp-sass with:
npm uninstall --save-dev gulp-sass
npm install --save-dev gulp-sass#2
You’ve probably tried to reinstall node-sass while using
npm install node-sass
or
npm uninstall node-sass
npm install node-sass
But node-sass is a C version of Sass. You have to use npm rebuild:
npm rebuild node-sass
I fixed this issue by deleting the existing /node_modules folder and running npm update
This is the only solution that worked for me,
sudo npm install -g n
sudo n 0.12.7
npm install node-sass#2
sudo npm -g install node-gyp#3
npm rebuild node-sass
This workaround (http://forum.ionicframework.com/t/error-running-gulp-sass/32311/20) worked form me.
Starting with this setup:
Cordova CLI: 5.3.3
Gulp version: CLI version 3.9.0
Gulp local: Local version 3.9.0
Ionic Version: 1.1.0
Ionic CLI Version: 1.6.5
Ionic App Lib Version: 0.3.9
ios-deploy version: Not installed
ios-sim version: 5.0.1
OS: Mac OS X Yosemite
Node Version: v4.1.1
Xcode version: Xcode 6.4 Build version 6E35b
I've found a solution to avoid to use 'sudo' command. We need before to fix npm permissions following this: https://docs.npmjs.com/getting-started/fixing-npm-permissions and fixing permissions for Node here: http://mawaha.com/permission-fix-node-js/ After this we can check and reinstall software without 'sudo' for npm, n or ionic.
I followed this step:
npm install -g n
rm -R node_modules/
npm install node-sass#3.3.3
npm -g install node-gyp#3
npm uninstall gulp-sass
npm install gulp-sass#2
npm rebuild node-sass
ionic setup sass
Why node-sass#3.3.3? Because it works with latest ionic version: https://github.com/driftyco/ionic/pull/4449
Combining the two answers above worked for me, plus additions:
sudo npm uninstall --save gulp-sass
npm install --save gulp-sass#2
npm update
npm rebuild node-sass
I have solved this to create the right directory with the specified binding.node file. You can download the bindings from github
https://github.com/sass/node-sass-binaries
Look in the error message the path where it tries to find the binding. In my case:
C:\Users\Martijn\Documents\node_modules\gulp-sass\node_modules\node-sass\vendor\win32-x64-46
So I create this map win32-x64-46 and copy the binding from github in.
My solution was to downgrade to v0.10.25 (try sudo n 0.10.25 if you use n)
For me, this issue was caused in my build system (Travis CI) by doing something kind of dumb in my .travis.yml file. In effect, I was calling npm install before nvm use 0.12, and this was causing node-sass to be built for 0.10 instead of 0.12. My solution was simply moving nvm use out of the .travis.yml file’s before_script section to before the npm install command, which was in the before_install section.
This was a Node version issue for me, try using nvm to backtrack your version to something like: 0.10.32. This worked for me. I was running 4.2.2
I solved this problem by updating my gcc from 4.4.x to 4.7.x
No need for sudo or re-installations. This has always worked for me:
nvm use 0.12.2
This is the steps I undertook to fix my issue.
I updated my node manually to the latest version
Reinstalled node-sass
npm install node-sass
3.npm audit fix to fix certain vulnerabilities.
`npm audit fix`
5.npm install node-sass
`npm install node-sass`
worked and compiled properly thereafter.
I apologize if anything related to my answer isn't right. I'm just a beginner.
Hope it works for you
