Use the secure installation method. Read the installation instructions — you probably want the single-user configuration. Use rvm list known to list available Rubies and then run rvm install x.x.x to install a specific version. Use rvm use x.x.x --default to change your default Ruby.
To switch between Ruby versions, run rvm use <version_number> (for example, rvm use 2.7.
Run the command which ruby. If you see a path such as /usr/bin/ruby, Ruby is installed. If you don't see any response or get an error message, Ruby is not installed. To verify that you have a current version of Ruby, run the command ruby -v.
