There are many reasons why you might need a different version of NodeJS.
For instance, running an app that relies on an older version of NodeJS.
NVM [↗] is a NodeJS version manager that makes it possible to do just that.
Follow this section of the ReadMe [↗] doc to install NVM.
Installing a specific version of NodeJS
Let's say we would like to install version 12 of NodeJS. We would run the following command to do so:
$ nvm install 12
Once you have different versions of NodeJS installed you can switch between them using the command below:
$ nvm use 12
You can also check which version of NodeJS you are running at any point in time:
$ node -v
