我最近开始从事一个从 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：

我的同事也在做这个项目，启动服务器似乎没有任何问题。他和我运行相同版本的 ruby​​、rails 和 WeBrick。

我尝试将语法从 key: 更改为 :key =>，但这应该不是问题，因为我正在运行 ruby​​ 版本 1.9.3。如果我无论如何进行更改，我会收到不同的错误消息：

我已经厌倦了完全删除和重新安装 rvm、ruby 和 rails 几次都没有成功。我也试过运行 bundle install 但没有帮助。

有谁知道出了什么问题？

谢谢

尝试将散列更改为 :key => :value 语法。在Rails 3.1 Deployment to Heroku Error中讨论了相同的错误和修复。建议的临时修复是：config/initializers/session_store.rb

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

config/initializers/wrap_parameters.rb

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

在您修复该行之后，看起来像另一行上的哈希语法。检查一下config/intializers/wrap_parameters.rb ，我想知道这个项目是否获得了“不”使用新语法的标志？
