Install node. js, NPM on Linux, and build with KARMA--ANGULARJS environment

Installing Nodejs

1. Build a dependent environment

　　　　First install the g++ compiler and Git, enter the following command in the terminal

sudo apt-get install g++ Curl Libssl-dev apache2-utils
sudo apt-get install Git-core

git does not need to be installed if it is already installed .

　　2. Install node. js

　　　Direct Input Command sudo apt-get install Nodejs installed is version 0.6, this will cause problems, resulting in the next installation of JS test tool karma, there is a problem.

So download and install the way to the official website to download http://nodejs.org

Click Install directly to download the standard version of node-v0.10.29

　　　　　　

Then, execute the Install command command

CD node-v0.10.29
　 　  ls View  within the node-v0.10.29 folder whether there is a configure this file, if not, it may not be the Standard Edition

sudo./configure errors may occur if you do not add sudo
sudo make This step may take a while
   sudo make install

　　Test whether the installation was successful

　　　Node--version

If v0.10.29 is the version number, the installation succeeds

Installing NPM

sudo apt-get install NPM

Installing Karma

sudo npm install-g karma wait patiently

As long as the installation of Nodejs is correct, then the next two steps will be very smooth, otherwise there will be error when installing Karma

Note: Be sure to add sudo before the command, otherwise there is no permission, prone to errors
