Javascript – Connect Redis using node JS in Linux

I’m trying to connect to redis in linux using Node js as shown below

var redis = require('redis');

However, you get an error similar to the following.
I installed redis-2.4.17 in linux at /home/masadmin/redis-2.4.17/src
Please help how to connect to redis using Node in linux.

module.js:340
    throw err;

Do you have a Node.js Redis module installed for your application? npm install redis (in the same directory as your application) will install it. See this screencast for more information.
