I'm becoming extremely frustrated with RubyMine, because getting the debugger to run is unacceptably difficult. I've got this in my gemfile,
gem 'ruby-debug-ide' if ENV["RM_INFO"]
gem 'ruby-debug-base19x', '0.11.30.pre12' if ENV["RM_INFO"]
(note that I do not have the debugger gem listed), and bundle install gives me, in part,
Using debugger-ruby_core_source (1.2.2)
Using ruby-debug-base19x (0.11.30.pre12)
Using ruby-debug-ide (0.4.16)
and this in Gemfile.lock
ruby-debug-base19x (0.11.30.pre12)
debugger-ruby_core_source (>= 1.1.4)
rake (>= 0.8.1)
ruby-debug-ide (0.4.16)
rake (>= 0.8.1)
Again, the debugger gem is nowhere to be found. So why do I still get this when I try to debug my Rails application?

Ensure your Gemfile contains this:
gem 'linecache19', '>= 0.5.13', :git => 'https://github.com/robmathews/linecache19-0.5.13.git'
gem 'ruby-debug-base19x', '>= 0.11.30.pre12'
gem 'ruby-debug-ide', '>= 0.4.17.beta17'
As described in my other answer the pre-release versions of the gems are required.
