Node

We are going to use nvm to manage the different versions of NodeJS and NPM.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

Close and open your terminal.

We install the latest stableversion of Node:

nvm install --lts

You can check it installed correctly by doing:

node -v
npm -v

Angular Cli

Test npm is working correctly by installing the Angular cli.

npm install -g @angular/cli

If you type ng, should display a similar message to this:
