After bundle install and ‘rails s’:

> /home/cthulhu/.rvm/gems/ruby-1.9.3-p194/gems/rack-mini-profiler-0.1.7/lib/mini\_profiler/storage/file\_store.rb:43:in `block in initialize': undefined method `instance’ for Rack::MiniProfiler:Class (NoMethodError)

And with

> Rack::MiniProfiler.config.storage = Rack::MiniProfiler::MemoryStore

It fails slightly different:

> /home/cthulhu/.rvm/gems/ruby-1.9.3-p194/gems/rack-mini-profiler-0.1.7/lib/mini\_profiler/storage/memory\_store.rb:17:in `block in initialize': private method `cleanup\_cache’ called for #Rack::MiniProfiler::MemoryStore:0x000000042295f8 (NoMethodError)

Rails 3.2.3  
I didn’t try with different apps/rails versions

I have no repro on Ruby 1.9.3 p194 with rails 3.2.3.

Can you include your Gemfile here so I can see if there is a conflict?

Really critical that I have Gemfile and Gemfile.lock to diagnose this stuff
