Rails服务器无法启动。宝石所有已安装的，我很困惑

Question

我今天去重新启动我的Rails服务器，当我去启动它备份这里是我的错误。我已经尝试了一切，并没有能够破解它。我卸载并重新安装了activesupport 3.1.0，似乎主动支持本身存在错误，我怀疑我可以修复。所以，让我感到困惑（让我感到困惑）。任何建议非常感谢。

你试图关于Ruby 1.8，特别是session_store哈希参数运行Ruby 1.9的代码。

通常情况下，当你创建一个新的Rails应用程序，它应该知道这一点，但我不知道你如何设置你的应用程序的具体情况（也许你克隆别人的？）。要创建一个应用程序，并迫使它使用1.8风格的散列，这样做：

rails new my_app --old-style-hash 

或者，您也可以使用像RVM或rbenv安装Ruby 1.9并使用它。
