尝试学习 Ruby on Rails 3 教程书，现在挂了：第 2.2 节

例子说：

rails generate scaffold User name:string email:string

我得到：

C:\Sites\rails_projects\demo_app>rails generate scaffold User name:string email:
string
C:/RailsInstaller/Ruby1.9.2/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:

        from <internal:lib/rubygems/custom_require>:29:in `require'
        from script/rails:5:in `<main>'

有人可以让我走上正确的轨道吗？谢谢！

我不知道你是否是 Rails 3 的新手，但如果不是，如果你是，我认为DEVISE是一个很好的使用宝石。我已经完成了这本书，我将 devise 用于我的身份验证系统。您需要做的就是从 github 手动安装它，以便阅读它的文档以及更多关于 ASCiiCast 和 railscast 的视频教程（与设计互动）。它作为书中使用的很多方法，例如，如果 signed_in、current_user、logged_in 等，并且还在使用DEVISE之前破坏用户模型。

我会查看您的 Gemfile 以查看您输入的所有内容是否正确。
