Running Zeus in Debugger with Rubymine

Question

This tutorial claims that running zeus in debug mode is as easy as clicking the debug button, however whenever I do I get the following error

Fast Debugger (ruby-debug-ide 0.4.22, debase 0.0.8) listens on 127.0.0.1:50192
1663: Exception in DebugThread loop: closed stream

What gives? What am I doing wrong?

Answer 1

This looks to be a bug that was fixed with RubyMine 6.0.1

Answer 2

Make sure to remove the debugger gem from your gemfile. You can make it conditional on whether RubyMine is running, like this:

unless ENV['RM_INFO']
  gem 'debugger'
end

See https://stackoverflow.com/a/11674999/278488 for more details.

Answer 3

If you add the debugger-xml gem, Rubymine will co-exist peacefully with the debugger. I'm running Zeus in the debugger from Rubymine 6.0.3, following the directions in the Rubymine Manual. You can then run the server or specs using the regular run command (not the debug run command) and zeus will launch it in the debugger. It's super fast to start up and a joy to use.
