npm WARN npm npm does not support Node.js v9.1.0

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
npm WARN npm can't make any promises that npm will work with this version.
npm WARN npm Supported releases of Node.js are the latest release of 4, 6, 7, 8, 9.
npm WARN npm You can find the latest version at https://nodejs.org/
/usr/local/Cellar/node/11.8.0/bin/gatsby -> /usr/local/Cellar/node/11.8.0/lib/node_modules/gatsby-cli/lib/index.js
+ 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

Answer 2

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.

Had similar issue in ubuntu, below helped solving it.

1. Remove existing versions of npm and node:

   sudo apt --auto-remove purge npm
   sudo apt --auto-remove purge nodejs
   

2. Re-install node

Answer 4

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:

1. Uninstall npm.

   Mac:
   sudo npm uninstall -g npm
   
   Windows:
   npm uninstall -g npm
   

2. Install node from https://nodejs.org

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
