How to install nodejs in ubuntu

Installation method 1

Install dependency packages

The code is as follows:	Copy code
$ Sudo apt-get install g ++ curl libssl-dev apache2-utils python build-essential gcc

Download and Install

Note the installation version

The code is as follows:	Copy code
// Download $ Wget http://nodejs.org/dist/v0.10.24/node-v0.10.24.tar.gz // Extract: $ Tar-zxf node-v0.10.14.tar.gz $ cd node-v0.10.14 // Default installation: (in the home directory by default) $./Configure $ make $ sudo make install // Select the directory for installation (install nodejs in the/usr/local/node directory) $./Configure-prefix =/usr/local/node $ Make $ Sudo make install

Method 2

Step 1: install the dependency package
 

The code is as follows:	Copy code
// Install the compiler and runtime environment Sudo apt-get install g ++ curl libssl-dev apache2-utils

 
// Install git. If you download the source code directly, you can skip it.
Sudo apt-get install git-core

Step 2: obtain the node source code

1) go to the official website Direct Download: http://nodejs.org/#download node-v0.6.5.tar.gz
 

The code is as follows:	Copy code
// Extract Tar-zxf node-v0.6.5.tar.gz // Enter the decompressed folder Cd node-v0.6.5

2) git clone git: // github.com/joyent/node.git

 

The code is as follows:	Copy code
# Specify the version to be migrated out. If the version is not migrated out, the latest version will be installed. Git checkout v0.6.5 # Enter the node folder Cd node

Step 3: compile and install

1) do not specify the installation path in three steps

 

The code is as follows:	Copy code
./Configure Make (takes several minutes) Sudo make install

2) specify the installation path and install it in the/opt/node Directory. After installation, you must grant the permission to opt/node. Otherwise, the installation will fail.

The code is as follows:	Copy code
./Configure -- prefix =/opt/node Make Sudo make install

Step 4: set environment variables

The code is as follows:	Copy code
// If no environment variable is set, you can only run node in the bin directory Export PATH = $ PATH:/opt/node/bin

Step 5: test whether the node is successfully installed

The code is as follows:	Copy code
// The node version number is displayed, indicating that the installation is successful. Node-v

Step 6: install npm
 

The code is as follows:	Copy code
// Get it done in one sentence Curl http://npmjs.org/install.sh | sh // If it fails Curl http://npmjs.org/install.sh | sudo sh

Step 6: install express
 

The code is as follows:

Copy code

# Remember to add-gd. Otherwise, it will be installed in the current folder. Npm install express-gd #-G indicates to install it in the lib of NODE_PATH, and-d indicates to install dependency suites together. If?] If there is-g, the current directory will be installed (a node_modules folder will be created). You can compare the differences between the two through the following commands: Npm list-g Npm list

Step 7: Test express

The code is as follows:	Copy code
/Enter your working directory // Create a testapp application Express testapp Cd testapp Node app. js

All installed. Now you can enter the Node. Js fantasy world !!
