Q:

Node.js v14.0.0 not supported by npm

I've recently installed newest version of node 14.0.0 on my computer (macOS Catalina). Wanted to start new project with. Initially I wanted to install express with npm install --save express and got below warning logs:
npm WARN npm npm does not support Node.js v14.0.0
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 6, 8, 9, 10, 11, 12, 13.
npm WARN npm You can find the latest version at https://nodejs.org/
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN ProjectName@1.0.0 No repository field.

I am wondering if this is issue on my setup side and I should reinstall node (possibly downgrade?) or something different.
Thank you for you patience and support!

A:

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
