ActionController :: RoutingError（沒有路線匹配[GET]「/」）：

我正在玩弄使用獨角獸和導軌的教程。我對rails完全陌生，爲了本教程的目的，我爲該項目所做的所有工作都是bundle exec rails new rails-starter，不需要進一步修改應用程序。ActionController :: RoutingError（沒有路線匹配[GET]「/」）：

當我運行bundle exec unicorn -c config/unicorn.rb -E production我在瀏覽器中得到的消息：

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

日誌顯示：

但是，如果我只是通過bundle exec rails server我可以運行Rails應用程序通過[IP]:3000成功訪問

我懷疑這個錯誤是與ActionController::RoutingError (No route matches [GET] "/"):有關的，但是我缺乏鐵軌知識來弄清楚這個問題。

您需要在routes.rb文件中設置根路由。

root :to => 'index#index'

其中第一個索引是控制器名稱（索引控制器）和第二索引在IndexController動作的名稱。

我將上面的代碼行添加到'routes.rb'中，但是錯誤仍然存在。 – kaizenCoder

重新啓動你的服務器.. – emaillenin

好吧，現在我有以下錯誤：ActionController :: RoutingError（未初始化的常量IndexController）：' – kaizenCoder

ActionController :: RoutingError（沒有路線匹配[GET]「/」）：
