I go to Settings - Ruby SDK and Gems, and pick out C:\RailsInstaller\Ruby1.9.3\bin\ruby.exe.

It loads up a bunch of gems on the right side, and looks like it's going to work.

I hit OK, and still have awful syntax highlighting and it still thinks it has no Ruby interpreter.

I've tried invalidating the cache, and even downloading a new version of ruby and pointing it to the new binary ruby.exe file.

  1. close RubyMine
  2. delete .idea/ folder
  3. re-open project in RubyMine
