How to upgrade and Update Node.js and NPM Safely

update_node_npm_osx.md

Here's how I successfully upgraded from v0.8.18 to v0.10.20 without any other requirements like brew etc, (type these commands in terminal):

sudo npm cache clean -f (force) clear you npm cache

sudo npm install -g n install "n" (this might take a while)

sudo n stable upgrade to lastest version

Note that sudo might prompt your password.

If the version number doesn't show up when typing node -v, you might have to reboot.
