With RVM, developers can easily install, manage, and switch between different versions of Ruby, as well as create and manage gemsets, which are collections of gems used for developing specific applications or projects.

RVM supports a wide range of Unix-based operating systems, including macOS, Linux, and BSD.

\curl -sSL https://get.rvm.io | bash -s stable
