Latest node.js & npm installation on Ubuntu 12.04

转自：https://rtcamp.com/tutorials/nodejs/node-js-npm-install-ubuntu/

Compiling is way to go for many but I am mostly in hurry so following works for me!

Adding Chris Lea’s Repo

Using Launchpad repo by Chris Lea just run following commands

apt-get install python-software-properties
apt-add-repository ppa:chris-lea/node.js
apt-get update

node.js install

apt-get install nodejs

Check node.js version

node -v

Outputs

v0.10.20

npm install

Above command should install npm.

Check npm version

npm -v

Outputs

1.4.3

If for some reason, if you see npm is not installed, you may try running:

apt-get install npm

   Followed your instructions, but I got the following error when trying to install npm:

   user@system:~$ sudo apt-get install npm
   
   Reading package lists… Done
   
   Building dependency tree
   
   Reading state information… Done
   
   Some packages could not be installed. This may mean that you have
   
   requested an impossible situation or if you are using the unstable
   
   distribution that some required packages have not yet been created
   
   or been moved out of Incoming.
   
   The following information may help to resolve the situation:

   The following packages have unmet dependencies:
   
   npm : Depends: nodejs but it is not going to be installed
   
   Depends: nodejs-dev
   
   Depends: node-request but it is not going to be installed
   
   Depends: node-mkdirp but it is not going to be installed

   Could it be my version of nodejs?

   user@system:~$ node -v

   v0.10.25
