Upgrade Node.js via NPM
Note: people have reported that this method can sometimes mess up module paths. Be careful with this upgrade (backup everything first) and do not attempt this with a complex node setup.
A better option may be to use NVM to manage node versions!
I was recently installing a utility via NPM when I learned that my version of Node.js itself was out of date.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:
It's quite nice that you can upgrade Node.js right from npm; it's like Inception...or something.
