Rubymine - enable line numbers

Question

Does anybody know how I can enable line numbers for Ruby (and Ruby on Rails as well) projects?

Answer 1

This setting is located in File | Settings (Preferences on Mac) | Editor | Appearance | Show line numbers:

Answer 2

On Rubymine 7.1, using a Mac, I found it under:

• Preferences --> Editor --> General --> Appearance

Near the top is a Show line numbers checkbox. See illustration.
