问题:

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!

回答1:

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


回答2:

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
