Sharing the process of building a Nodejs development environment in Ubuntu

System environment:

Ubuntu 12.04 LTS 64bit

1. Install nodejs through apt-get - failed (you can see the source code installation method below):

Copy the codeThe code is as follows:

~ sudo apt-get install nodejs
~ sudo apt-get install npm

~ node -v
v0.6.12

~ npm -v
1.1.4

Create a working directory

Copy the codeThe code is as follows:

~ mkdir workspace
~ mkdir workspace/nodejs
~ cd workspace/nodejs
~ pwd
/home/conan/workspace/nodejs

Installation failed

npm not ok

System prompts that node and npm versions are incompatible. Maybe it's a problem that the apt-get source has not been updated.

2. Download the source code from github and install it successfully

Below you need to find a compatible version and install it manually.
Uninstall the newly installed node and npm first

Copy the codeThe code is as follows:

~ sudo apt-get autoremove npm
~ sudo apt-get autoremove nodejs
Find the official release download of nodejs: /joyent/node

In ubuntu, install git first

Copy the codeThe code is as follows:

~ sudo apt-get install git

Then, download the nodejs source code from github

Copy the codeThe code is as follows:

~ git clone git:///joyent/
Cloning into 'node'...

remote: Compressing objects: 100% (28074/28074), done.

Resolving deltas: 100% (78807/78807), done.

Enter the node directory

Copy the codeThe code is as follows:

~ cd node
~ pwd
/home/conan/workspace/nodejs/node

Switch the latest release version v0.11.2-release

Copy the codeThe code is as follows:

~ git checkout v0.11.2-release
Branch v0.11.2-release set up to track remote branch v0.11.2-release from origin.
Switched to a new branch 'v0.11.2-release'

Carry out installation

Copy the codeThe code is as follows:

./configure
make
sudo make install

Installation is complete, view node version

Copy the codeThe code is as follows:

~ node -v
-bash: /usr/bin/node: No such file or directory

The prompt is error, the node is not found, check the node installation location

Copy the codeThe code is as follows:

~ whereis node
node: /usr/local/bin/node

Add soft links: node and npm to /usr/bin

Copy the codeThe code is as follows:

~ sudo ln -s /usr/local/bin/node /usr/bin/node
~ sudo ln -s /usr/local/bin/npm /usr/bin/npm

Let's check the node and npm versions again

Copy the codeThe code is as follows:

~ node -v
v0.11.2
~ npm -v
1.2.21

Install express below

Copy the codeThe code is as follows:

Installation was successful.

3. Establish an express project and start the first project

Copy the codeThe code is as follows:

~ express -e nodejs-demo
create : nodejs-demo
create : nodejs-demo/
create : nodejs-demo/
create : nodejs-demo/public
create : nodejs-demo/public/javascripts
create : nodejs-demo/public/images
create : nodejs-demo/public/stylesheets
create : nodejs-demo/public/stylesheets/
create : nodejs-demo/routes
create : nodejs-demo/routes/
create : nodejs-demo/routes/
create : nodejs-demo/views
create : nodejs-demo/views/
install dependencies:
$ cd nodejs-demo && npm install
run the app:
$ node app

Install dependency package

Copy the codeThe code is as follows:

Start the program

Copy the codeThe code is as follows:

~ node 
Express server listening on port 3000

Test whether curl is successfully started

Copy the codeThe code is as follows:

~ sudo apt-get install curl
~ curl localhost:3000

<!DOCTYPE html>
<html>
<head>
<title>Express</title>
<link rel='stylesheet' href='/stylesheets/' />
</head>
<body>
<h1>Express</h1>
<p>Welcome to Express</p>
</body>
</html>

Nodejs server log:

Copy the codeThe code is as follows:

GET / 200 6ms - 206b

OK, we have successfully prepared the nodejs development environment in ubuntu. Now you can enjoy the development fun.
