Solution 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.

Solution 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

       Please see this article for troubleshooting help:
       http://devcenter.heroku.com/articles/rails31_heroku_cedar#troubleshooting

Solution 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.

Solution 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

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:

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

From what I had understood, I thought when I ran the precompile command, that it would compile all of the SASS files into one CSS file. Is this not the case? (I'm so new at this, but loving it)

I don't think the SASS from the gem you are using gets precompiled, I'm not sure anyway.

I think you've found the answer. Thank you very much.
