nvm makes it easy to switch between different versions of Node.js. Read more about it on the project's GitHub page.
Once you have nvm installed, if you want to install the latest version of Node v12 just run:
nvm install 12If you have multiple versions of Node.js installed on your workspace, you can switch to a specific version by writing:
nvm use 10.19.0Make a Node version default
In order to set a default version of Node for your workspace, just type:
nvm alias default 12Where the latest version of 12 is the version you want to be used by default.
