I had to add config.ru to the repository. Rails 3 has some new components which must be included in your git push.
One way to figure out what's missing is to compare your app with a new, empty Rails 3 app. "git ls-files" lists the files in your git repository. A commit with nothing changed produces a list of untracked files. If any untracked file matches one in a new, empty app, or git ls-files doesn't include every filename in an empty app, then you have to add something to your tracked file set. Use "git add". Thanks to those who helped out. -- You received this message because you are subscribed to the Google Groups "Heroku" group. To post to this group, send email to her...@googlegroups.com.
