I am getting this message “Ruby (Rack) application could not be started” when I attempt to run my application on Apache with Phusion Passenger. Under Webrick it runs just fine. This is what appears on the screen: # File ``` Line Location ``` 0 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb 31 in `gem_original_require' 1 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb 31 in `require’ 2 /home/pjt/quote/config/boot.rb 4 3 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb 31 in `gem_original_require' 4 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb 31 in `require’ 5 /home/pjt/quote/config/application.rb 1 6 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb 31 in `gem_original_require' 7 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb 31 in `require’ 8 /home/pjt/quote/config/environment.rb 2 9 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb 31 in `gem_original_require' 10 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb 31 in `require’ 11 [config.ru](http://config.ru) 3 12 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/builder.rb 46 in `instance_eval' 13 /home/pjt/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/gems/1.8/gems/rack-1.1.0/lib/rack/builder.rb 46 in `initialize’ 14 [config.ru](http://config.ru) 1 in `new’ 15 [config.ru](http://config.ru) 1 Any idea what the problem is?

There’s normally an actual error above that, you’ve posted the stack trace (which is useful after you know what the error is). Cheers, Andy – Andy J.

Just curious if you tried removing the “[config.ru](http://config.ru)” file from your rails application’s root directory? It seems to be a different error than me but I thought I would throw it out there just in case it helps. My environment is: FreeBSD 6.4 Ruby 1.9.1p378 Passenger 2.2.11 Rails 3.0.0.beta3 ---

Hi, I was getting the same error as you, I did try install rails 3 beta 3 with some ruby versions, also tryed to install with the new passenger 2.2.12 available on Github, but always getting an error like that. Or just ruby crash when trying to load a simple scaffold or trying to see information throu “About your application’s environment”. Passenger says that could’t load the rack gem and ask me to install it, but it has already installed. Even adding the GEM\_PATH to the .bashrc file. I google it a lot, spent lot of time with no result. I think that maybe the best thing to do is wait for the final version. ## Kleber S.

Sounds like a different problem then. Passenger would not start at all for me with the [config.ru](http://config.ru) file intact. Dan ---
