ruby-on-rails - Rails::WelcomeController#index twitte bootstrap 中的 ArgumentError

Question

我一直在使用 rails 4 和 ruby 1.9.3 进行开发，我使用的是 twitter bootstrap 教程，http://railscasts.com/episodes/328-twitter-bootstrap-basics现在尝试加载我的应用程序时出现以下错误，任何人都可以帮助解决这个问题，我尝试了 get "welcome/ index" 和根目录：'welcome#index' 在我的 route.rb 文件中。

这是我的欢迎控制器、框架跟踪、routes.rb 和 gem 文件：

我在 Ruby 2.0 中运行的 twitter 引导程序没有问题。您可以在 Ruby 2.0 中尝试。
