ActionController :: RoutingError（没有路线匹配[GET]“/”）：

我正在玩弄使用独角兽和导轨的教程。我对rails完全陌生，为了本教程的目的，我为该项目所做的所有工作都是bundle exec rails new rails-starter，不需要进一步修改应用程序。ActionController :: RoutingError（没有路线匹配[GET]“/”）：

当我运行bundle exec unicorn -c config/unicorn.rb -E production我在浏览器中得到的消息：

The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved.

但是，如果我只是通过bundle exec rails server我可以运行Rails应用程序通过[IP]:3000成功访问

我怀疑这个错误是与ActionController::RoutingError (No route matches [GET] "/"):有关的，但是我缺乏铁轨知识来弄清楚这个问题。

您需要在routes.rb文件中设置根路由。

root :to => 'index#index'

其中第一个索引是控制器名称（索引控制器）和第二索引在IndexController动作的名称。

我将上面的代码行添加到'routes.rb'中，但是错误仍然存在。 – kaizenCoder

重新启动你的服务器.. – emaillenin

好吧，现在我有以下错误：ActionController :: RoutingError（未初始化的常量IndexController）：' – kaizenCoder
