运行rails服务器时发生OpenID错误

我在完成了教程，并尝试启动rails服务器。在运行rails服务器几秒钟后，我遇到了一个错误，我正在努力找出原因。以下是错误消息的一个片段：

 /usr/lib/ruby/gems/1.8/gems/activesupport-3.0.7/lib/active_support/dependencies.rb:239:in
 `require': no such file to load --
 openid/store/fetchers (LoadError)
         from /usr/lib/ruby/gems/1.8/gems/activesupport-3.0.7/lib/active_support/dependencies.rb:239:in

什么是

openid/store/fetchers

？我看到其他一些教程提到“require”，那么为什么会导致这个错误呢？

我也遇到了同样的问题，我认为这与您的omniauth版本有关。在gem文件中显式指定omniauth的版本，否则可能会得到版本0.0.1或其他奇怪的东西。参考
