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](http://0.0.0.0:3000)

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?

It seems to be a RadRails issue.

Running debug sevrer from a terminal window and rails console from  
another one works well.
