When trying to debug a Rails 3 app with RadRails 2.0.4, I''m running into a problem with gem loading, apparently. See below for a stack trace. That problem disappears, when I move Gemfile out of the way, but, of course, then other necessary gems aren''t loaded. From my Debug Configuration Project: <myproject> File: script/rails Working Directory: /home/michael/aptana/<myproject> Interpreter Arguments: -e STDOUT.sync=true -e STDERR.sync=true -e load(ARGV.shift) Programm Arguments: server --debugger --environment=development -- port=3000 Interpreter: standard /usr/bin/ruby I''ve tried adding/removing ruby-debug and ruby-debug-ide to the Gemfile in any order and at the top-level as well as in the :development group. I think, but are far from sure, that RadRails and Bundler are of devided minds as to which gems are active when. First, RadRails directly runs rdebug-ide, which runs script/rails which causes bundler to mangle which gems are active. In the file, where the error occurs, there''s a require ''ruby-debug/processor'' and that succeeds. But possibly it loads the wrong file, i.e. not the one from ruby-debug, but the one from ruby-debug-ide. The later does indeed not define Debugger::CommandProcessor. (I''m using Ruby 1.8.7 and this might matter here.) I''ve tried my luck with the latest beta of Aptana Studio 3 as well, but that wasn''t a pleasant experience, either. I''m hoping someone has an idea how to get around this problem. I''m also taking suggestions for other Linux-based(!) IDEs with suitable debugging abilities :-( Michael Fast Debugger (ruby-debug-ide 0.4.9) listens on :2984 /var/lib/gems/1.8/gems/ruby-debug-0.10.3/cli/ruby-debug.rb:9 /var/lib/gems/1.8/gems/bundler-0.9.26/lib/bundler/runtime.rb:46:in `require'' /var/lib/gems/1.8/gems/bundler-0.9.26/lib/bundler/runtime.rb:46:in `require'' /var/lib/gems/1.8/gems/bundler-0.9.26/lib/bundler/runtime.rb:41:in `each'' /var/lib/gems/1.8/gems/bundler-0.9.26/lib/bundler/runtime.rb:41:in `require'' /var/lib/gems/1.8/gems/bundler-0.9.26/lib/bundler/runtime.rb:40:in `each'' /var/lib/gems/1.8/gems/bundler-0.9.26/lib/bundler/runtime.rb:40:in `require'' /var/lib/gems/1.8/gems/bundler-0.9.26/lib/bundler.rb:89:in `require'' /home/michael/workspace/ue_guidelines/config/application.rb:7 /var/lib/gems/1.8/gems/railties-3.0.0.beta4/lib/rails/commands.rb:28:in `require'' /var/lib/gems/1.8/gems/railties-3.0.0.beta4/lib/rails/commands.rb:28 /var/lib/gems/1.8/gems/railties-3.0.0.beta4/lib/rails/commands.rb:27:in `tap'' /var/lib/gems/1.8/gems/railties-3.0.0.beta4/lib/rails/commands.rb:27 ./script/rails:6:in `require'' ./script/rails:6 /var/lib/gems/1.8/gems/ruby-debug-ide-0.4.9/lib/ruby-debug- ide.rb:109:in `debug_load'' /var/lib/gems/1.8/gems/ruby-debug-ide-0.4.9/lib/ruby-debug- ide.rb:109:in `debug_program'' /var/lib/gems/1.8/gems/ruby-debug-ide-0.4.9/bin/rdebug-ide:87 /var/lib/gems/1.8/bin/rdebug-ide:19:in `load'' /var/lib/gems/1.8/bin/rdebug-ide:19 -e:3:in `load'' -e:3 Uncaught exception: uninitialized constant Debugger::CommandProcessor -- Michael Schuerig mailto:michael-q5aiKMLteq4b1SvskN2V4Q@public.gmane.org http://www.schuerig.de/michael/ -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
