And I ran this command : rake db:migrate : and rake aborted!!

undefined method `debug_rjs=' for ActionView::Base:Class

Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)
I'm on windows!!

i removed
#config.action_view.debug_rjs = true from configuration/environment/development.rb
and everything went fine!!

Thanks for posting the solution pradeepbicc

For others, I'm moving an app between rails 2 to rails 3, so perhaps that's the cause.
