我运行了一个bundle install，并且因为无法在终端内成功运行rails s。我是新来的铁路，并试图找到这方面的帮助，但没有人能以101的方式向我解释。发生了什么问题 - 看起来这是一个NameError？Rails服务器将无法运行 - 未初始化的常量使用（NameError）
=> Call with -d to detach
=> Ctrl-C to shutdown server

你可以发布配置/ routes.rb的内容（它似乎在错误中提到了几次，所以可能会导致问题）？ – michaelrshannon 2013-03-03 19:04:15
您在“捆绑安装”（如果有）之前添加，修改或更新了哪些宝石？ – scones 2013-03-03 19:05:34
