问题:

I'm using Twitter's Bootstrap translated to SCSS files. It works in local-development, but when I precompile and push to Heroku (using Cedar stack), I get this:

> Started GET "/" for 74.57.16.130 at 2012-01-28 17:16:36 +0000

I'm using Rails 3.2.0, the app was working on Heroku until I added the SASS files.

回答1:

Are you using a gem? Make sure your gem is not part of the assets group and is accessible in production.

From GemFile

# Gems used only for assets and not in production environments by default.

So just move the gem outside of any group and you should be okay.



回答2:

Just put this in your gemfile

gem "twitter-bootstrap-rails", "~> 2.0rc0"

There's invalid CSS in BootStrap 2.0 which causes SCSS compilation to fail

You can verify this by looking at the output of 

git push heroku master

You should see some error like:

-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile
       rake aborted!
       Invalid CSS after "...er-radius:0 \0/": expected expression (e.g. 1px, bold), was ";}"
       (in /tmp/build_1k8ugei34dpcw/app/assets/stylesheets/application.css)

       Tasks: TOP => assets:precompile:primary
       (See full trace by running task with --trace)
       Precompiling assets failed, enabling runtime asset compilation
       Injecting rails31_enable_runtime_asset_compilation
       Please see this article for troubleshooting help:
       http://devcenter.heroku.com/articles/rails31_heroku_cedar#troubleshooting


回答3:

In config/environments/production.rb add this line:

config.assets.precompile = [/^[-_a-zA-Z0-9]*\..*/]

My guess is it is not adding all your assets.



回答4:

this solved the issue in heroku at least

just downgrade to sass-rails 3.1.4

group :assets do
  gem 'coffee-rails', '~> 3.1.1'
  gem 'uglifier', '>= 1.0.3'
  gem 'sass-rails', '3.1.4'
  gem 'bootstrap-sass', '~> 2.0.2'
end


回答5:

When you see something like this when you are deploying rails app to heroku.com

Precompiling assets failed, enabling runtime asset compilation
...
could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port xxxx?

Just add this to config/application.rb

config.assets.initialize_on_precompile = false


回答6:

Make sure, in config/environments/production.rb, you have...

config.serve_static_assets = true
