运行rails服务器时出错

Question

我正在尝试为我的rails博客应用程序配置声明授权。根据需要完成所有工作后，我开始使用rails来启动服务器。我遇到了以下错误。

rails s

    from script/rails:6:in `require' 
    from script/rails:6 

我的博客应用程序有点类似于这个blog应用程序。

请帮助解决此问题。谢谢。 ：） -

编辑：关于使用authlogic的评论后。这里有一个具有相同错误的另一github上页：

https://github.com/binarylogic/authlogic/issues/316

取代你authlogic宝石的代码如下：

gem "authlogic", :git => "git://github.com/binarylogic/authlogic.git"

这是一个轨道兼容性错误。看看这个页面GitHub的与错误：
