Error when trying to use debugger in RubyMine

Question

I've installed all the gems needed to run the debugger in my Rails app, but I get the following error. I have require 'ruby-debug' in development.rb.

Error:

If you want to debug with RubyMine, remove all debugging-related gems from your Gemfile and don't require them anywhere. RubyMine's debugger doesn't need any support from your project, and it's possible that including debugging stuff in your project could break RubyMine's debugger, perhaps due to version clashes. (I believe the ruby-debug gem works only with Ruby 1.8, and I see you're using 1.9.)
