RubyMine 2018.3 Help

Configuring Ruby Interpreter

RubyMine enables you to choose the required Ruby interpreter for a current project or newly created projects. The IDE automatically detects interpreters installed on a local machine and maintained by version managers. Moreover, you can add additional local or remote interpreters (Docker, Vagrant, SSH, etc.).

The following interpreters are supported:

  • Ruby MRI (version 1.8.7 and later)

  • JRuby

  • Rubinius (without debugging)

Select Ruby Interpreter

To configure Ruby SDK for the current project, follow these steps:

  1. Invoke the Settings/Preferences dialog (Ctrl+Alt+S) and go to the Ruby SDK and Gems page.

  2. (Optional) If RubyMine has multiple projects opened, select the required one to define a Ruby interpreter.

  3. Choose the required Ruby interpreter. You can also choose the gemset for the RVM and rbenv version managers.
