uninitialized constant Rack::RubyProf

[Holger Schmeisky]

Hi,

I am trying to run  ruby-prof on a rails 2.3.10 application, and after adding

config.middleware.use Rack::RubyProf, :path => '/home/deploy/profile', :min_percent => 0

to production.rb I get an error when accessing the application via the browser:

Error message:

uninitialized constant Rack::RubyProf

Exception class:

NameError

Rubyprof is installed correctly on the system, it is added to the gemfile and "bundle install" lists it as installed. I installed it the same way on a Rails 3 deployment and it worked fine. Is there any difference how I should configure it in Rails 2?

Regards,
Holger

For the googlers: I added require 'ruby-prof' to the production.rb, that helped. Maybe there is a difference between how Rails 2 and Rails 3 require gems...
