Answer 2

You install nvm first (Node Version Manager):

https://github.com/nvm-sh/nvm

Then you say nvm install <version>.

And when you want to upgrade... it's as easy as nvm install <version>

And you can switch between Node versions:

nvm use <version>`

And by adding a .nvmrc file into the root of your project, you can wire up your shell to automatically switch to the version of Node.js specified in the .nvmrc file.
