Installing Specific version of NodeJs in Ubuntu using NVM

Steps For installing Specific Version of Ubuntu using NVM

In Order to install specific version of node in ubuntu we will be using a tool called NVM which stands for node version manager.

NVM helps us to install and manage multiple versions of node in a single machine.It helps to switch between different versions 

To install NVM , Run below commands in a terminal

• sudo apt-get update
• sudo apt-get install build-essential libssl-dev
• curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.31.0/install.sh | sh

To gain access to the nvm functionality, you'll need to log out and log back in again, or you can source the~/.profile file so that your current session knows about the changes:

source ~/.profile

Now that you have nvm installed, you can install isolated Node.js versions.

To find out the versions of Node.js that are available for installation, you can type:

nvm ls-remote
nvm install 6.0.0

You can change to what ever version you like.

Usually, nvm will switch to use the most recently installed version. You can explicitly tell nvm to use the version we just downloaded by typing:

nvm use 6.0.0

When you install Node.js using nvm, the executable is called node. You can see the version currently being used by the shell by typing:

node -v

If you have multiple Node.js versions, you can see what is installed by typing:

nvm ls

If you wish to default one of the versions, you can type:

nvm alias default 6.0.0

To remove / uninstall a version

nvm uninstall 6.0.0

To Exeute node REPL/command line with specific version

nvm run 6.0.0

In NVM, you can also use alias for setting the default version of node

nvm alias default 6.0.0.

Each version of Node.js will keep track of its own packages and has npm available to manage these.

You can learn more about the options available to you with nvm by typing:
