我正在尝试将我的应用部署到Heroku，但收到以下错误。
我的Ruby / Rails版本是：
-Rails 4.0.0
-ruby 2.0.0p247（2013-06-27修订版41674）[x86_64-darwin12.3.0]
我添加了'rails_12factor'宝石，这是另一个SO问题的建议解决方案，但这不起作用。我还将其设置为true，因为另一个SO问题，config.serve_static_assets = true，但这也不起作用。

你的css文件中有错误：
Invalid CSS after "...-233px -51px; }": expected "}", was ""
(in /tmp/build_26a3cf6f-5411-4847-a502-be0a4ee03280/app/assets/stylesheets/application.css)
(sass):18950
修复＆amp;再次运行部署。如果仍然无效，请回复部署日志。

不得不在css文件的末尾添加'}'，不知道它丢失了......
