I've been trying to move an app from Rails 2.3.8 to 3.0.3. The 2.3.8
version runs fine on Heroku. Modified for Rails 3.0.3, it runs on my
Windows/MySQL development machine.
But I haven't been able to get it to run at all on Heroku. "bundle
install" runs clean, and "git push" runs clean. All I get from Heroku
is "App crashed".
In the console log (below), Rails can't find "dispatcher". But I
don't see "dispatcher" or "dispatcher.rb" is in the file tree. What's
missing? If I'm missing a Gemfile entry, how can I find out what it
is?
Thanks very very much for any help at all!
