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：

我的同事也在研究这个项目，并没有启动服务器的任何问题 . 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 =>，这应该不是问题，因为我正在运行ruby版本1.9.3 . 如果我无论如何都要进行更改，我会收到不同的错误消息：

/Users/thomas/.rvm/gems/ruby-1.9.3-p194/gems/activesupport-3.2.3/lib/active_support/dependencies.rb:245:in `load': /Users/thomas/Projects/BillingMiddleware/config/initializers/wrap_parameters.rb:8: syntax error, unexpected ':', expecting kEND (SyntaxError)

我已经厌倦了几次彻底删除和重新安装rvm，ruby和rails几乎没有占上风 . 我也试过运行捆绑安装，但没有帮助 .

有谁知道出了什么问题？

谢谢

ruby-on-rails ruby syntax gem rvm

    尝试将哈希值更改为：key =>：value syntax . Rails 3.1 Deployment to Heroku Error讨论了相同的错误和修复 . 建议的临时修复程序是：config / initializers / 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]

    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"not"的标志使用新的语法？
