Question

当我尝试运行命令时使用rails 2.3.5：script/generate scaffold user user_name:string email:string，我收到错误：

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

我搜索过此错误，但我发现唯一的解决办法就是在environment.rb

取消注释这一行

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

在我的环境中已经取消注释。我该怎么办？

一个新手的故障:)，我来自rails 3，我已经安装了bundle以便能够在我的rails 2项目中安装宝石但是我不知道我应该在使用bundler的情况下再次评论上面的行因为在添加bundler的说明中没有提及。

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

然后我得到以下

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

      exists  app/controllers/
      exists  app/helpers/

       route  map.resources :users

      exists    app/models/
      exists    test/unit/
      exists    test/fixtures/
      create    app/models/user.rb
      create    test/unit/user_test.rb
      create    test/fixtures/users.yml
      create    db/migrate
      create    db/migrate/20130820214343_create_users.rb

和rake db:migrate完成了，这意味着一切都很好吗？
