I am facing this problem upon pushing my app to Heroku:
- 500 internal server error
- ActionView::Template::Error...application.css isn't precompiled (see attached Heroku logs)
- Also, ActionController::RoutingError (No route matches [GET] "/assets/rails.png"
I am using Twitter Bootstrap 2.0.1 and Rails 3.1.1 (see Gemfile below)
Any guidance would be much appreciated!

HEROKU INFO
=== weddoo
Addons: Shared Database 5MB
Database Size: 64k
Dynos: 1
Git URL: git@heroku.com:weddoo.git

Repo Size: 11M
Slug Size: 11M
Stack: bamboo-mri-1.9.2
Web URL: http://weddoo.heroku.com/
Workers: 0
So based upon the heroku info that you provided I see that you are on the bamboo stack and that stack does not support Rails 3.1+. Only the cedar stack supports Rails 3.1+. You'll need to use the following command to create a new app on the cedar stack:
heroku create --stack cedar
This is the result of your stylesheets not being compiled. Heroku will attempt to run
rake assets:precompile
before deploying your app. If the precompile command fails it will fail silently for now. I actually have an open issue for this on Heroku
https://github.com/heroku/heroku-buildpack-ruby/issues/9
The most likely cause is that the Rakefile is trying to load (or access) a gem. Heroku buildpacks attempt to compile the stylesheets before they have access to the gemset so any requires will fail. The best way to avoid this is to wrap those requires in your Rakefile in environment specific conditionals:
if Rails.env == 'development' || Rails.env == 'test'
require 'somegem1'
require 'somegem2'
# whatever code is being used by those gems goes in this block
end
