apt install nodejs nodejs-legacy

Node Version Manager

Some times application need different version of Node.Js than the one provided with your OS. You can install different version of Node.Js by using Node Version Manager (nvm). You can find more details on nvm at http://nvm.sh.

To install nvm, run

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash

Example

root@git:~# curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash

=> Appending nvm source string to /root/.bashrc
=> bash_completion source string already in /root/.bashrc
=> You currently have modules installed globally with `npm`. These will no
=> longer be linked to the active version of Node when you install a new node
=> with `nvm`; and they may (depending on how you construct your `$PATH`)
=> override the binaries of modules installed with `nvm`:

/usr/local/lib
`-- nvm@0.0.4
=> If you wish to uninstall them at a later point (or re-install them under your
=> `nvm` Nodes), you can remove them from the system Node as follows:

     $ nvm use system
     $ npm uninstall -g a_module

=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
root@git:~# 

Install Specific version of Node.js with nvm
