您的

应用程序.rb

文件中有一个错误

检查以下行：

C:\Sites\demo_app>rails generate scaffold User name:string email:string
C:/Sites/demo_app/config/application.rb:7:in `<top (required)>': undefined metho
d `groups' for Rails:Module (NoMethodError)
        from C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/gems/railties-3.0.9
/lib/rails/commands.rb:15:in `require'
        from C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/gems/railties-3.0.9
/lib/rails/commands.rb:15:in `<top (required)>'
        from script/rails:6:in `require'
        from script/rails:6:in `<main>'

它们应该被替换为

if defined?(Bundler)
  Bundler.require(*Rails.groups(:assets => %w(development test)))
end

根据NeoRiddler的说法

Bundler.require(:default, Rails.env) if defined?(Bundler)
