ruby-on-rails - 更新的 rails 3 到 4 不会查看 gems 资产

Question

我踩到奇怪的问题。我有 bootstrap-sass gem（以及其他一些 js）。当我试图访问我得到的任何页面时

File to import not found or unreadable: bootstrap-responsive.

Load paths:
  /Users/alex/Projects/feedbackhunter/app/assets/images
  /Users/alex/Projects/feedbackhunter/app/assets/javascripts
  /Users/alex/Projects/feedbackhunter/app/assets/stylesheets

正如加载路径所说，rails 不会查看所有这些文件所在的 bootstrap-sass gem 资产。我做错了什么？
