如何檢查Heroku的錯誤

我不熟悉破譯這意味着什麼。這是我的第一個應用程序。

Answer 1

你運行了所有的遷移並設置了環境變量嗎？在您的網站上啓用Papertrail。然後你可以查看應該顯示錯誤的日誌。

Answer 2

查看這裏發生的最好的方法是通過閱讀日誌。您可以通過運行做到這一點：

heroku logs -a limitless-fortress-32820 (or whatever you named your app) 

你這樣做你的命令行，這假定您已經安裝了heroku cli工具。 檢查日誌顯示的錯誤並從那裏開始。它可能是一個procfile，環境變量問題，遷移問題或任何數量的事情。

Answer 3

要實時檢查Heroku的日誌：

heroku logs -t -a limitless-fortress-32820 

進行以下檢查以解決問題： 1.你是否使用PG數據庫？ 2.是否所有遷移文件都運行？
