ruby-on-rails - 尝试启动 Rails 服务器时出现语法错误

Question

我最近开始从事一个我从 github 克隆的项目。

每次我尝试启动 Rails 服务器时，我都会收到以下错误:

 /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/session_store.rb:3: syntax error, unexpected ':', expecting $end (SyntaxError)

我的同事也在做这个项目，启动服务器似乎没有任何问题。他正在运行与我相同版本的 ruby​​、rails 和 WeBrick。

我已经尝试将语法从 key: 更改为 :key =>，这应该不是问题，因为我运行的是 ruby​​ 版本 1.9.3。如果我无论如何进行更改，我都会收到不同的错误消息:

我厌倦了完全删除并重新安装 rvm、ruby 和 rails 好几次都没有成功。我也试过运行 bundle install 但没有帮助。

有谁知道出了什么问题吗？

谢谢

尝试将您的散列更改为 :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:配置/初始化程序/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]
