Uninstall node.js on CentOS 6 7

Yes node has an uninstaller !

Get the .tar.gz of the release you have, for example for 0.10.46
https://github.com/nodejs/node/releases/tag/v0.10.46
Assuming it is downloaded in your your home ~/

$> tar -xzvf node-0.10.46.tar.gz
$> cd node-0.10.46
$> sudo make uninstall

Note in my case I had to reboot otherwise CentOS 6 was still trying to access the unexisting "node" and "npm" instead of just saying "". This was messing up some build scripts; so a reboot is needed.To just uninstall npm

$> sudo npm uninstall npm -g
