Ruby on rails Rails、Desive和Mongo-我应该使用哪些版本？

我目前正在尝试让Mongo数据库与Desive一起运行。我使用的是Rails 3.2.2和Ruby 1.9.3、mongo_mapper 0.11.0、devise 1.1.9和devise-mongo_mapper 0.0.2。我在网上查阅了很多资料，但它们似乎总是过时的

我现在面临的一个大问题涉及Desive-mongo_mapper。在终端上运行mongod的情况下，尝试运行rails服务器会得到以下结果：

/usr/local/lib/ruby/gems/1.9.1/gems/devise-1.1.9/lib/devise.rb:193:in `mailer=': undefined method `ref' for ActiveSupport::Dependencies:Module (NoMethodError)
from /usr/local/lib/ruby/gems/1.9.1/gems/devise-1.1.9/lib/devise.rb:195:in `<module:Devise>'

因此，基本上，旧的设计将无法工作，而最新版本与我当前的设计mongo_mapper不兼容。这有什么办法吗？无论是一种让所有这些程序协同工作的方法，还是一种根本不需要Desive-mongo_mapper的方法，都将是非常好的。

他们只是在gempec中修改了版本，代码可能不会更改。

您可以使用

-v参数安装任何版本的gem

sudogem安装任何东西-v1.0.1

或者你可以看看塑料鸡建议的叉子。
我也遇到了同样的错误，运行“捆绑更新”解决了我的问题。
为什么不使用？它由Desive直接支持。不需要其他宝石。谢谢！在其中一个fork上进行了更改，我的服务器现在正在运行。
