部署腳手架導軌應用程序Heroku。 「heroku開放」給出「你正在尋找的頁面不存在」

Question

Windows 7，今天從railsinstaller.org重新安裝最新的rails版本。 「heroku推」成功。 數據庫遷移成功。 「heroku open」給出「你正在尋找的頁面不存在」

我已經部署使用Rails 4之前，並沒有任何問題。就是今天。

請幫忙！

感謝

Answer 1

它看起來並不像你有一個錯誤 - 只是你沒有爲根的路由。即。像這樣的東西在routes.rbroot 'home#index'。

PS。請注意，Rails 4在生產中做了一些奇怪的事情 - 它的行爲與開發模式不同，並且期望定義明確的根路由。
