Posted in Good guide for standing up a solid Ruby gem development environment in Visual Studio Code?
Check out the official Ruby installation guide by Ruby site. I will recommend using rbenv if you are OS X or Linux user. Windows user may install Ruby by downloading the Ruby installer for Windows. I’m a OS X user, Ruby is pre-installed in OS X. However, I would recommend ruby developer to use rbenv to manage your development environment as it will not mess with the version of system installed Ruby runtime.
