[SOLVED] How to yum install Node.JS on Amazon Linux

Issue

I've seen the writeup on using yum to install the dependencies, and then installing Node.JS & NPM from source. While this does work, I feel like Node.JS and NPM should both be in a public repo somewhere.

How can I install Node.JS and NPM in one command on AWS Amazon Linux?

Solution

Stumbled onto this, was strangely hard to find again later. Putting here for posterity:

sudo yum install nodejs npm --enablerepo=epel

EDIT 3: As of July 2016, EDIT 1 no longer works for nodejs 4 (and EDIT 2 neither). This answer (https://stackoverflow.com/a/35165401/78935) gives a true one-liner.

EDIT 1: If you're looking for nodejs 4, please try the EPEL testing repo:

sudo yum install nodejs --enablerepo=epel-testing

EDIT 2: To upgrade from nodejs 0.12 installed through the EPEL repo using the command above, to nodejs 4 from the EPEL testing repo, please follow these steps:

sudo yum rm nodejs
sudo rm -f /usr/local/bin/node
sudo yum install nodejs --enablerepo=epel-testing

The newer packages put the node binaries in /usr/bin, instead of /usr/local/bin.

And some background:

The option --enablerepo=epel causes yum to search for the packages in the EPEL repository.

EPEL (Extra Packages for Enterprise Linux) is open source and free community based repository project from Fedora team which provides 100% high quality add-on software packages for Linux distribution including RHEL (Red Hat Enterprise Linux), CentOS, and Scientific Linux.
