I was following some tutorial that was recorded a while ago, and it said for us to downgrade our npm version to 5.5.1 to avoid any differences (since that was the newest version at the time of the recording). So I did, using classic
npm install -g npm#5.5.1
However, now I'm stuck, I can't update to the actual present day latest version. I tried npm install -g npm#latest, I tried manually typing the latest version, I even tried uninstalling both Node and NPM, and installing the latest ones, fresh from the site, but for whatever reason my npm just gets stuck on 5.5.1 again. How do I fix this?
I'm using Windows btw. Also, I'm just learning about Node and NPM, so I guess there is a chance I'm missing some obvious solution?
Edit: whenever I try to install something, I get the following
npm WARN npm npm does not support Node.js v12.18.3
npm WARN npm You should probably upgrade to a newer version of node as we

uninstall node (Settings -> Add or remove programs), then navigate to C:\Users\{User}\AppData\Roaming and delete the npm and npm-cache folder and finally install node again (using the installer).
You are missing the -g. You said:
I tried npm install npm#latest
but that that doesn't include the -g. The -g is key because it causes npm to be installed globally (best rhyme). See Downloading and installing packages globally. Your first command includes it, but not the follow up.
Because of this, you probably install npm as a local dependency (which you probably didn't mean to do). Check your package.json and see if there is any listing of npm. If you aren't directly using runtime pieces of npm, remove that dependency and just install the specific version you want globally with -g.
In your project root directory, run the update command:
npm update

Thank you for you patience and support!
Try :
Mac:
sudo npm uninstall -g npm // uninstalls globally
Windows:
npm uninstall -g npm // uninstalls globally
Then:
Re-install node
NOTE: Ensure that your PATH points to where node is installed
e.g. If node installed at /usr/local/bin/node, ensure /usr/local/bin is in your PATH
For windows. Follow this instructions here https://github.com/coreybutler/nvm-windows
PREREQUISITE: Uninstall existing node & npm
Install nvm-windows
Run nvm install <version>
Run nvm use <version>
This happens due to dependencies from libraries like Heroku or yarn etc.., . Another hack-of-a-solution if you are stuck on this issue on MAC or any unix based system is:
Step 1: cd /Users/username/
Step 2: Do a ls -ltrh to list hidden files and locate .npm/ and .npm-packages/
Step 3: Sudo rm -rf .npm/
Step 4: Sudo rm -rf .npm-packages/
Step 5: Run brew reinstall node
Step 6: Run npm install -g npm#7.13.0 or any other version if there is a minor update needed
Step 7: Run npm install -g #angular/cli or any other framework to test
Step 8: Check versions node -v and npm --version
This issue should now be resolved.
on windows:
*Uninstall node.js (Windows Add/Remove programs)
*Manually delete the npm folder from your user profile (%APPDATA%/roaming/npm)
*Install node.js (from Windows 10 LTS download MSI)
I'm using nvm-windows version 1.1.7.
I just installed node 11.9.0.
nvm installs npm version 6.5.0 together with this node version.
However, there's npm version 6.7.0 available already.
When I now do npm i -g npm I get:
npm ERR! path C:\Program Files\nodejs\npm.cmd
npm ERR! code EEXIST
npm ERR! Refusing to delete C:\Program Files\nodejs\npm.cmd: is outside C:\Program Files\nodejs\node_modules\npm and not a link
npm ERR! File exists: C:\Program Files\nodejs\npm.cmd
npm ERR! Move it away, and try again.
I found no way to avoid this.
This is a duplicate from my answer here: https://stackoverflow.com/a/50955293/491553
Here is how I upgrade npm when running nvm-windows:
cd %APPDATA%\nvm\v14.20.0 # or whatever node version you're using
move npm npm-old
move npm.cmd npm-old.cmd
move npx npx-old
move npx.cmd npx-old.cmd
cd node_modules\
move npm npm-old
cd npm-old\bin
node npm-cli.js i -g npm#latest --force
And boom, upgraded.
Several workarounds are available in this Issue on the nvm-windows github repo:
https://github.com/coreybutler/nvm-windows/issues/300
There are examples using DOS, PowerShell, bash, and batch scripts.
I have windows 10 operating system.
I installed in following way.
cd %APPDATA%\nvm\v8.11.3
move npm 5.6.0
move npm.cmd 5.6.0.cmd
cd node_modules\
move npm 5.6.0
cd 5.6.0\bin
node npm-cli.js i -g npm#latest
I had to force it :-/
When it came to
node npm-cli.js i -g npm#latest
I'd rather had to use
node npm-cli.js i -g npm#latest --force
probably to overcome a permission error involved in overwriting the "C:\Program Files\nodejs" link.
download this updateNpm.bat file
open powershell in that same folder and run this command updateNpm.bat latest
I tried the script and other solutions, this by far is the easiest way:
Navigate to the relevant Node folder (cd C:\Users\yourUser\AppData\Roaming\nvm\vxx.xx.x)
rename npm -> npm2
rename npm.cmd -> npm2.cmd
rename npx -> npx2
rename npx.cmd -> npx2.cmd
Run npm2 install -g npm#your-version
the new npm will create npm, npm.cmd, npx, npx.cmd files, so you can remove the previous renamed files
I also found it necessary to install windows-nvm to c:\nvm and c:\nodejs to prevent issues with unsupported paths with spaces.
rm C:\nodejs\npm*
rm C:\nodejs\npx*
mv C:\nodejs\node_modules\npm C:\nodejs\node_modules\npm-old
node C:\nodejs\node_modules\npm-old\bin\npm-cli.js i -g npm#next
For me I only get the problem when updating npm with npm v6.
So using a newer version of npm via npx to run the upgrade works for me.
For the very newest version
npx npm install -g npm
Or use a specific version
npx npm#7 install -g npm#7
I faced this problem today, the way i solved it was installing latest node with nvm then copying the npm files from latest to the version i am on.
nvm install latest
cd AppData/Roaming/nvm/LATEST
xcopy npm.cmd ../LTS && xcopy npm ../LTS && xcopy node_modules/npm ../LTS
I then confirmed it working by trying to compile my code that breaks on latest.
This worked for me:
curl -L https://npmjs.org/install.sh | sh
If you already have git bash installed, use it there.
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
npm WARN npm npm does not support Node.js v11.8.0
npm WARN npm You should probably upgrade to a newer version of node as we

+ 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 installed the node as new version. once i installed i checked in cmd for like this:
C:\Users\Mohamed.Arif>node --version && npm --version
v0.10.35
1.4.28
But after I installed the node, npm I am trying to install the latest yeoman. in their website, i noted the npm version requires v2.1.0+ - i confused here. how to i install the npm as they requested?
I am running the latest version of node only.
Install prerequisites
Before installing Yeoman, you will need the following:
Node.js v0.10.x+
npm (which comes bundled with Node) v2.1.0+
git
You can check if you have Node and npm installed by typing:
http://yeoman.io/codelab/setup.html
What is wrong here? I am working with windows7.
Thanks in advance!
See How do I update npm on Windows?
tl;dr - npm -g install npm does work, but the old version of npm is still in your PATH.
Option 3: navigate to C:\Program Files (x86)\nodejs with cmd.exe and then run
the installation without -g:
npm install npm
