Upgrade Node.js via NPM (original) (raw)

This method of upgrading node is now unstable and should not be used. The best way to manage Node.js versions is to use NVM: Node Version Management.!

I was recently installing a utility via NPM when I learned that my version of Node.js itself was out of date. No worries -- simply upgrade my Node.js install and move forward. Of course I could just hit nodejs.org and get the new image, but figured there had to be an easier way. It turns out there is -- you can upgrade your local Node.js with NPM:

sudo npm cache clean -f sudo npm install -g n sudo n stable

The n package represents a Node helper, and running the last command upgrades node to the latest stable version. Instead of using "stable", you could specify a desired version:

sudo n 0.8.21

Once your install is complete, you can confirm you version with another command:

node -v

It's quite nice that you can upgrade Node.js right from npm; it's like Inception...or something.
