Ubuntu 14.04 Install Node.js

Node.js is an open source platform for server-side programming using JavaScript, Ubuntu 14.04 is a commonly used Linux operating system. This article explains how to install Node.js on Ubuntu 14.04.

Step 1: Update the package manager

Before starting to install Node.js, we need to update the package manager first. Use the following command to update:

sudo apt- get update

Step 2: Install Node.js

The easiest way to install Node.js is to install it through the apt-get command:

sudo apt-get install nodejs

However, in Ubuntu, Node.js commands use node instead. You also need to install npm (Node package manager):

sudo apt-get install npm

Step 3: Create a symbolic link

Even if nodejs is already installed, we still need to install it. You need to create a symbolic link to use the node command:

sudo ln -s /usr/bin/nodejs /usr/bin/node

This will create the nodejs symbol in /usr/bin link, and create a "node" command in the system so that it points to nodejs.

Step 4: Verify whether the Node.js installation is successful

In order to verify whether the Node.js installation is successful, you can use the following command:

node -v

This should return the version number of Node.js, indicating a successful installation.

Step 5: Upgrade npm

Although npm has been installed in step 2, because the installed version may be older, npm needs to be upgraded. This can be done using the following command:

sudo npm install -g npm

This command will update npm using npm itself so that it is up to date.

Summary

Now you have installed Node.js and created a symbolic link to enable the node command to work. You also verified that the Node.js installation was successful, and finally updated npm to the latest version. At this point, you have completed all the steps to install Node.js on Ubuntu 14.04.
