How To Install NVM (Node Version Manager) on Fedora

Node Version Manager (NVM) allows you to quickly install and manage node.js versions.

I have written guides on how to install NVM on other operating systems:

Install NVM on Fedora

Install the Script

Shell

Refresh the terminal window

Shell

Verify that the installation is complete

Shell

We can now check which version of NVM has been installed

Shell

This will print out the version number to screen.

It’s a good idea to check out the commands the are available :

Shell

Install Node.JS

We now have the capability of installing and using any number of different Node.JS versions on our work station.  For instance we can install versions 5, 4 or even 0.12

Shell

You can choose any version of node that is available and NVM will download a pre-built binary version of Node.JS and install it. Once install is complete NVM will display which version has been installed.

Shell

You can confirm this by asking node which version has been installed

Shell

Set a Default version

If you want to ensure that the same version of node is used next time you log in or access vai SSH, you can set a default

Shell

Switch between versions

Now that we have multiple versions of node installed, we may need to switch between them as and when we need to.

Shell

** Note that when switching between node versions, the associated npm version and any global npm packages will be changed as well. You may need to reinstall your global npm packages when switching to a recently installed version.

Get a list of installed version of node

To get a list of all the versions of node you have installed via the nvm simple use the following command
