Apple bundles the Ruby programming language with OS X. However, the main caveat for using the bundled version, called the system Ruby, is that Apple bundles Ruby for it’s own use. Therefore, it’s best not to make changes to the system Ruby. On Linux/UNIX, you can use the package management system of your distribution or third-party tools (rbenv and RVM). On macOS machines, you can use third-party tools (rbenv and RVM). On Windows machines, you can use RubyInstaller. See the Installation page for details on using package management systems or third-party tools.
