I'm moving an old and very complicated Rails 2 application to Rails 3 on Heroku... After hundreds of code changes it mostly runs OK with Rails 3.0.3 locally (on Windows). But uploading it to Heroku just produces "App crashed". The Heroku console error message complains that there's no ".../mnt/config/application" file to load. Heroku receives the push, reports that "Your bundle is complete!" and "Compiled slug size is 37.3MB"
Any suggestions? Thank you very much for your attention. ... >heroku logs --app mydev /usr/ruby1.8.7/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- /disk1/home/slugs/ 378263_1bf16dc_9972-b394afee-890f-4334-b9f4-05e5193bc410/mnt/config/ application (LoadError) from /usr/ruby1.8.7/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:31:in `require' from /disk1/home/slugs/378263_1bf16dc_9972-b394afee-890f-4334- b9f4-05e5193bc410/mnt/config/environment.rb:2 from /usr/ruby1.8.7/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:31:in `gem_original_require' from /usr/ruby1.8.7/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:31:in `require' from /usr/ruby1.8.7/lib/ruby/gems/1.8/gems/thin-1.2.6/lib/rack/ adapter/rails.rb:42:in `load_application' from /usr/ruby1.8.7/lib/ruby/gems/1.8/gems/thin-1.2.6/lib/rack/ adapter/rails.rb:23:in `initialize' from /home/heroku_rack/heroku.ru:29:in `new' from /home/heroku_rack/heroku.ru:29 from /home/slugs/378263_1bf16dc_9972-b394afee-890f-4334- b9f4-05e5193bc410/mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/lib/rack/ builder.rb:46:in `instance_eval' from /home/slugs/378263_1bf16dc_9972-b394afee-890f-4334- b9f4-05e5193bc410/mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/lib/rack/ builder.rb:46:in `initialize' from /home/slugs/378263_1bf16dc_9972-b394afee-890f-4334- b9f4-05e5193bc410/mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/lib/rack/ builder.rb:63:in `new' from /home/slugs/378263_1bf16dc_9972-b394afee-890f-4334- b9f4-05e5193bc410/mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/lib/rack/ builder.rb:63:in `map' from /home/heroku_rack/heroku.ru:18 from /home/slugs/378263_1bf16dc_9972-b394afee-890f-4334- b9f4-05e5193bc410/mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/lib/rack/ builder.rb:46:in `instance_eval' from /home/slugs/378263_1bf16dc_9972-b394afee-890f-4334- b9f4-05e5193bc410/mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/lib/rack/ builder.rb:46:in `initialize' from /home/heroku_rack/heroku.ru:11:in `new' from /home/heroku_rack/heroku.ru:11 from /home/slugs/378263_1bf16dc_9972-b394afee-890f-4334- b9f4-05e5193bc410/mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/lib/rack/ builder.rb:46:in `instance_eval' from /home/slugs/378263_1bf16dc_9972-b394afee-890f-4334- b9f4-05e5193bc410/mnt/.bundle/gems/ruby/1.8/gems/rack-1.2.1/lib/rack/ builder.rb:46:in `initialize' from /home/heroku_rack/heroku.ru:1:in `new' from /home/heroku_rack/heroku.ru:1 ==> dyno-3674715.log (crash) <== /usr/ruby1.8.7/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- ...
