刚开始一个新应用，想试试 Rails 4.0.0.RC1
在阅读了有关该主题的一些迁移教程后，我让该应用程序使用 Ruby 2.0、Rails 4.0.0.RC1、Bootstrap with Sass、Devise ... 和一些自定义 sass 样式表进行开发。
今天我尝试部署到 Heroku。该应用程序有效，但我的资产有一些问题。不应用任何样式（也不显示图像）。
部署时，我可以在日志中看到资产已预编译，但是当我启动应用程序时，它们没有加载。我收到以下错误：

我已经用谷歌搜索了这个问题并尝试了一些我发现但没有成功的解决方案。已经尝试预编译资产并包括 Heroku 的 gem：gem 'rails_log_stdout'，github：'heroku/rails_log_stdout' gem 'rails3_serve_static_assets'，github：'heroku/rails3_serve_static_assets'
有什么建议么？
