Question

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

Answer 1

What worked for me - On Ubuntu

Install nodejs

sudo apt install nodejs

Install npm

curl -L https://www.npmjs.com/install.sh | sudo sh

Answer 2

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)

Answer 3

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

Answer 4

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.

Answer 5

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.

Answer 6

If you are unable to uninstall npm, instead you can skip that step and just
