的Rails 4.0：ActionController的:: RoutingError

當我開始在生產模式serven，我得到這個頁面：的Rails 4.0：ActionController的:: RoutingError

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

應用程序不能正常工作時的發展模式。

這裏是我的日誌：

你可以列出你的路由在這裏提交內容請？ – 2013-04-22 07:40:14

當您在開發模式下點擊「/」時，是否顯示靜態索引頁？ – manoj 2013-04-22 09:23:59

ty，我以爲rails 4會自動生成索引頁。 – vladimirich 2013-04-23 06:00:18

在Rails 4.0.0部署到生產的時候，你將需要生成/創建索引頁應位於在public/index.html中。

我已經使用此修復方法成功部署在Amazon EC2（AWS）上。

例如：

$ rails generate controller welcome index
