我正在尝试使用带有mongoid和devise的rails4。我在我的Gemfile中有这个
gem 'rails', '4.0.0'
gem 'mongoid'
gem 'devise'
bundle install
成功。但是当我尝试启动rails server
时,我收到此错误

我遇到了同样的问题,只需在Gemfile中进行以下更改
gem 'mongoid', github: 'mongoid/mongoid'
如果Devise继续出现问题,也可以改变设计
gem 'devise', github: 'plataformatec/devise', branch: 'rails4'
这解决了我的问题。

运行
bundle update
如果这不起作用,请尝试包含轻便摩托车宝石
gem 'moped'
