Hello sir…!!

Good morning to all of u…!!!

Friends. I have download some projects from [rubyforge.com](http://rubyforge.com). Now some is  
running as usual means all migration files are running and table is  
also created. But in one application when i run

rake db:migrate

then its give some errors like

rake is aborted…!!  
No such file to load --ruby-debug

then second thing is… I’m running this application in windows  
platform. When i’m going to start server in development run mode then  
its not started then i changed the run mode and make Production  
instead of Development. Then its started. plz give me the right  
suggestion

Thanks…!!  
.

check if u are using any plugins in your application.

first, install those plugins  
and then restart the serevr.

try installing the “ruby-debug” gem

“gem install ruby-debug”  
this is used as an alternative to the built-in “breakpoint” function.

alternatively search through /config/environment.rb, and  
/config/environments/development.rb, and any plugins  
/vendor/plugins/\*/init.rb

look for any lines saying “require ‘ruby-debug’” or “Debugger.start”

these are only useful if you’re using the functions of ruby-debug, if  
you don’t care, then delete them.
