当我尝试运行命令时使用 rails 2.3.5 时script/generate scaffold user user_name:string email:string，我得到了错误：

uninitialized constant Rails::Generator::GeneratedAttribute::ActiveRecord

我已经搜索了这个错误，我发现唯一的解决方案是在我的environment.rb

config.frameworks -= [ :active_record, :active_resource, :action_mailer ]

这在我的环境中已经没有注释了。我能做些什么？

新手的错 :)，我来自 rails 3，并且我已经安装了 bundle 以便能够在我的 rails 2 项目中安装 gem，但我不知道如果使用 bundler，我应该再次评论上面的行'在添加捆绑器的说明中没有提及。

发表评论# config.frameworks -= [ :active_record, :active_resource, :action_mailer ] 后，我得到以下信息

➜  ~  script/generate scaffold user user_name:string email:string

      create    test/unit/user_test.rb
      create    test/fixtures/users.yml
      create    db/migrate
      create    db/migrate/20130820214343_create_users.rb

并且rake db:migrate完成了，这意味着现在一切都很好？
