ruby script console error in edge version

Hi,

I try to play with edge version of rails. Maybe someday I could be rails contributor. :slight_smile: Ok, based on rails recipe books by martin, I do this: $ rails example_rails_hack (I have rails 1.2 version) $ cd example_rails_hack/vendor $ svn co http://svn.rubyonrails.org/rails/trunk rails

The fast way to play with this edge version is through console. So.... $ cd .. $ ruby script/console

But I got this error: Loading development environment. /home/knight/work/code/ruby/example_rails_hack/vendor/rails/ activerecord/lib/../../activesupport/lib/active_support/ dependencies.rb:477:in `const_missing':NameError: uninitialized constant ActionController::Base::DEPRECATED_INSTANCE_VARIABLES /home/knight/work/code/ruby/example_rails_hack/app/controllers/ application.rb:6:NoMethodError: undefined method `session' for ApplicationController:Class

Any idea how to fix this?

Thank you.
