Sometimes you need to have several different versions of Node installed on your computer because different projects need different versions. If you need to be able to do this, or if you just want an easier way to install Node, use Node Version Manager (nvm).
Go to the GitHub homepage: https://github.com/nvm-sh/nvm
Follow the installation instructions: https://github.com/nvm-sh/nvm#install-script.
The easiest way is just to copy the command beginning with
and paste it into your command line
Important Note ⚠
bash (like you just did) can be unsafe if you do not trust where the command is coming from. Always be careful when copy/pasting commands from the internet!
nvm install YOUR_NODE_VERSION to install a version of Node. Once it's installed nvm will switch to using the version you installed. You can check by running
nvm ls. You will see a list of all the versions of Node you have installed with nvm. The arrow points the version that you are currently using.
If you know a version of Node is already installed on your computer, you can switch to it by running
nvm use YOUR_NODE_VERSION.
