Upgrade Node.js to the latest version on Mac OS

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 the terminal):

1. sudo npm cache clean -f (force) clear you npm cache
2. sudo npm install -g n install n (this might take a while)
3. sudo n stable upgrade to the current stable version

Note that sudo might prompt your password.

Additional note regarding step 3: stable can be exchanged for latest, lts (long term support) or any specific version number such as 0.10.20.

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