ubuntu安装node.js

How
to install the latest node.js on Ubuntu?

Node.js is an event-based and non-blocking I/O framework — built on Chrome’s JavaScript engine. Its goal is to provide an easy way to build scalable network programs.

In most linux distributions Node.js is available in a repository which can be accessed via a package manager such as 

apt-get

 or 

aptitude

.

However in the repository of the brand new Ubuntu 12.10 (Quantal Quetzal) the 

nodejs

 package
has the version number 0.6.19 while the current version is 0.8.14 as of this writing. Unfortunately many nodes — that’s how node.js applications are called — are constantly under development and often depend on a newer version.

If you are trying to install a node with the 

node
package manager

 but providing an old node environment, you most probably expierence a similar error message to the one below.

npm ERR! error installing ws@0.4.22
npm WARN This failure might be due to the use of legacy binary "node"
npm WARN For further explanations, please read

Preparation

The nodejs package depends on a couple of other packages, be sure that you have the repository component universe enabled.

# in /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu quantal main restricted universe
deb http://security.ubuntu.com/ubuntu quantal-security main restricted universe
deb http://archive.ubuntu.com/ubuntu quantal-updates main restricted universe

After enabling it run 

sudo
apt-get update

.

Installation steps

In order to get a more recent 

nodejs

 version
you need to add a personal package
archive (ppa) and update the package index files. To do so open Terminal and
execute the following commands.

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

Pay attention to the second line, if you are trying to execute 

apt-apt-repository

 you
won’t have luck.

Install the node package manager

Update (March 15th, 2013)

You no longer need to install npm separately as nodejs includes it now.

To manage your nodes it’s recommended to install the node package manager (npm) too.

sudo apt-get install npm

Who prefers to compile
npm from its sources will find this
script very useful.

Update (March 20th, 2013)

It looks like somebody forgot to pay his bill. The link to the script is currently broken.
