未定義的方法`load_routes！'在rails3中使用設計與mongoid

Question

我有一個使用MongoDB的Rails應用程序。爲了連接MongoDB，我使用了mongoid gem，現在我想集成用於驗證的設計。

我使用

gem 'mongoid-devise' 
gem 'devise' 

bundle install後，我做的事：

rails g devise:install 

但它拋出一個錯誤，象下面這樣：

/home/user/.rvm/gems/ruby-1.9.3-p194@new_banter_it/gems/activesupport-3.2.6/lib/active_support/core_ext/module/aliasing.rb:31:in `alias_method': undefined method `load_routes!' for class `ActionDispatch::Routing::RouteSet' (NameError)

請幫我找出該怎麼做ASAP ...

沒有必要使用mongoid-devise是非常古老的一個，這就是爲什麼它不與Rails3中

devise只運行就足夠了，因爲它支持mongoid也因爲你可以看到這裏devise。
