Rails4 +设计+ mongoid - `require':无法加载这样的文件 - mongoid/version(LoadError)

Question

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是成功的.但是当我尝试启动时rails server,我得到了这个错误

我在Ubuntu上使用Ruby 2.0.0

Answer 1

我遇到了同样的问题,只需在Gemfile中进行以下更改即可

gem 'mongoid', github: 'mongoid/mongoid'

如果Devise继续存在问题,也可以改变设计

gem 'devise', github: 'plataformatec/devise', branch: 'rails4'

这解决了我的问题.
