How to install NPM on ubuntu 14.04?

Question

Node.js

I wrote the command sudo apt-get install npm and after that it gives an error.
What to do?
Some packages cannot be installed. Perhaps you are asking for the impossible,
or you are using an unstable version of the distribution where the
packages you requested have not yet been built or have been removed from Incoming.

node.js installed

Answer 1

I advise you to use the latest stable release from ppa:

sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install python-software-properties python g++ make nodejs

npm comes in the same package as nodejs
