我最近开始研究一个我从github克隆的项目。

每次我尝试启动rails服务器时都会出现以下错误：

我的同事也正在研究该项目，并且启动服务器似乎没有任何问题。他和我一样运行相同版本的ruby，rails和WeBrick。

我已经尝试从key更改语法：to：key =＆gt;，这应该不是问题，因为我正在运行ruby版本1.9.3。如果我做了那个改变，我得到一个不同的错误信息：

我已经厌倦了几次彻底删除并重新安装rvm，ruby和rails几乎没有占上风。我也尝试过运行捆绑安装但没有帮助。

有没有人知道出了什么问题？

答案 0 :(得分：5)

尝试将哈希值更改为：key =＆gt; ：值语法。 Rails 3.1 Deployment to Heroku Error讨论了相同的错误和修复。 建议的临时修正是： 配置/初始化/ session_store.rb 

App::Application.config.session_store :cookie_store, :key => '_BillingMiddleware_session'

配置/初始化/ wrap_parameters.rb 

ActionController::Base.wrap_parameters :format => [:json]

答案 1 :(得分：1)

在修复该行之后，在另一行上看起来像哈希语法。检查config/intializers/wrap_parameters.rb，我想知道这个项目是否得到“不”使用新语法的标志？
