Environment problem..!!

Hello sir..!!

Good morning to all of u..!!!

Friends. I have download some projects from 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.
