From: Fritz Trapper Date: 2009-12-25T21:20:00+09:00 Subject: undefined method `run_init_script' for Debugger:Module I'm new with ruby and rails. My environmant is RadRails running on Ubuntu 9.04 with ruby 1.8.7 After I started the debug server from RadRails, I got this output Fast Debugger (ruby-debug-ide 0.4.5) listens on localhost:44275 => Booting Mongrel (use 'script/server webrick' to force WEBrick) => Rails 2.1.0 application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server ** Starting Mongrel listening at 0.0.0.0:3000 ** Starting Rails with development environment... ** Rails loaded. ** Loading any Rails specific GemPlugins ** Signals ready. TERM => stop. USR2 => restart. INT => stop (no restart). ** Rails signals registered. HUP => reload (without restart). It might not work well. ** Mongrel 1.1.5 available at 0.0.0.0:3000 ** Use CTRL-C to stop. Looks well. But executing a debugger statement in my controller, rails crashes with this message: undefined method `run_init_script' for Debugger:Module The first backtrace line is: /var/lib/gems/1.8/gems/ruby-debug-base-0.10.3/lib/ruby-debug-base.rb:239:in `debugger' The next is the debuger line in my controller. How to fix this? -- Posted via http://www.ruby-forum.com/.
