Rails app works locally, crashes on Heroku

I've been trying to figure out what's going wrong from the logs, but have no idea how to fix it. Here are the snippets from the logs I'm a little confused as to how to fix. Any help would be greatly appreciated.

Could not load SystemTimer >= v1.2.0. Falling back to timeout.rb. SystemTimer is STRONGLY recommended for timeouts in Ruby 1.8.7. See http://ph7spot.com/blog/system-timer-1-2-release for details.

/app/.bundle/gems/ruby/1.8/gems/activesupport-3.1.0/lib/active_support/dependencies.rb:306:in `depend_on': No such file to load -- spec_helper (LoadError)

and this was at the top of the logs

from /app/.bundle/gems/ruby/1.8/gems/railties-3.1.0/lib/rails/initializable.rb:49:in `run_initializers'

According to bundle, the following gems are being used

According to bundle install, the following gems are installed

Thanks!

I had the same thing. Turns out during development a spec had somehow gotten copied up into into the controllers folder. Didn't have any affect locally, but crashed cedar...

I think the problem might be in this line:

/app/.bundle/gems/ruby/1.8/gems/activesupport-3.1.0/lib/active_support/dependencies.rb:306:in `depend_on': No such file to load -- spec_helper (LoadError)

It seems that one of your initializers has require "spec_helper" in it (or loads a file elsewhere that does the same) and shouldn't. This might have to do with gems in your Gemfile that are in the :test group that don't get loaded by default on Heroku.

You might try running bundle install --without test development locally to reproduce how Heroku is installing the gems. Note that this will be the permanent way that bundle installs gems until you delete the ./.bundle/config file from your project, so you will want to do that afterwards once you've figured things out.

Hope this helps...

Had the same issue with passenger. The problem was a require in a model that depended on a lib. Adding the lib directory to autoload and removing all requires (found by fgrep 'require' -r app/) worked.
