Installing Node via Node Version Manager on Ubuntu


 
 
Node Version Manager allows you to install different versions of Node.js.
 
Installation instructions are here:

 
 We basically need to download and run a bash script:

$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash

=> Compressing and cleaning up git repository

=> Appending nvm source string to /home/bojan.komazec/.bashrc
=> Appending bash_completion source string to /home/bojan.komazec/.bashrc
=> 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" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

 

After this, re-open the terminal and type:

$ nvm

Node Version Manager (v0.39.2)

Note: <version> refers to any version-like string nvm understands. This includes:
  - full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
