How to Install Node.js via NVM (Node Version Manager) on Fedora 21

Node.js is a cross-platform runtime environment, configurable on Linux, OS X, and Microsoft Windows, and built on JavaScript. Applications, both server-side and networking, are also written in JavaScript. Node.js lends itself nicely to quick deploying, real-time web applications, and is generally thought of as extremely scalable due to its event-driven architecture.

The Node Version Manager allows admins to easily manage node.js versions. It’s a bash script that has the capability to manage multiple active versions of node.js, with functionality such as: installation, executing commands with specific node.js versions, setting the PATH variable to use a specific node.js versions, etc.

Pre-Flight Check
  • These instructions are intended specifically for installing Node.js via NVM (Node Version Manager) on a single Fedora 21 node.
  • I’ll be working from a Liquid Web Self Managed Fedora 21 server, and I’ll be logged in as root.
  • If NVM is not already installed, then visit our tutorial on: How to Install NVM (Node Version Manager) for Node.js on Fedora 21

Step #1: Install tar

First, clean-up yum:

yum clean all

As a matter of best practice we’ll update our packages:

yum -y update

Installing tar is as simple as running just one command:

yum -y install tar

Step #2: Install NVM (Node Version Manager)

If NVM is not already installed, then visit our tutorial on: How to Install NVM (Node Version Manager) for Node.js on CentOS 7

Step #3: Check Available Node.js Versions

Versions that are available for installation:

nvm ls-remote

In addition to the versions listed by the output of that command, it is also possible to install the latest stable or unstable versions, as shown in the next step.

Step #4: Install a Node.js Version

To download, compile, and install the latest version in the v0.11.x release of node.js:

nvm install 0.11

To display currently activated version:

nvm current

Which gives me the output:

v0.11.16 (npm v2.3.0)

In this case I am now running v0.11.16.

To download, compile, and install the latest stable release of node.js, which in this case is v0.12.3:

nvm install stable

To display currently activated version:

nvm current

Now gives me the output:

v0.12.3

In this case I am now running v0.12.3.

nvm ls

Gives the following output:

v0.11.16
-> v0.12.3
node -> stable (-> v0.12.3) (default)
stable -> 0.12 (-> v0.12.3) (default)
unstable -> 0.11 (-> v0.11.16) (default)
iojs -> iojs- (-> N/A) (default)

And finally, if you want to modify PATH to use v0.11.16 again, then use the following command:

nvm use 0.11.16

Which returns:

Now using node v0.11.16 (npm v2.3.0)
