manage ruby versions

To manage Ruby versions, you can use a version manager like RVM (Ruby Version Manager) or rbenv. These tools allow you to install and switch between multiple Ruby versions on your system. Here are the general steps to manage Ruby versions using RVM:

  1. Install RVM or rbenv on your system.
  2. Use the version manager to install the desired Ruby version.
  3. Set the default Ruby version for your projects or globally.
  4. Use commands provided by the version manager to switch between Ruby versions as needed.
