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
