If you’re using an operating system other than macOS Sierra 10.12 or macOS High Sierra 10.13, my friend Chris Oliver has an extensive collection of tutorials on how to install Ruby.

Ruby version 2.0.0 comes installed on macOS Sierra. However, support for Ruby 2.0.0 ended on February 26, 2016. Also, as you begin to work on more Ruby projects, you’ll need to work with multiple Ruby versions. Luckily, several tools exist to help us install and manage multiple Ruby versions.

I’m glad you’re interested in using Ruby. Learning Ruby & Ruby on Rails changed my career in ways unimaginable. I’m excited for you!
