导读：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' 捆绑安装是成功的.但是当我尝试启动rails服务器时,我收到此错误 Exiting/home/username/.rvm/gems/ruby-2.0.0-p0/gems/activesupport-4.0

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'

捆绑安装是成功的.但是当我尝试启动rails服务器时,我收到此错误

Exiting

我在Ubuntu上使用Ruby 2.0.0

解决方法

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.
