Rails：Heroku第一次部署失敗

Question

我認爲問題在於我在使用SQLite3，所以我遷移到了PostgreSQL，但問題仍然存在。該應用在當地正常工作。我打開我的應用程序的Heroku與打開，它給了我下面的錯誤：

Application Error. An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details.. 

我試圖通過查看日誌來尋找解決方案，但是失敗了，所以我需要別人的幫助。 這裏是我的日誌，我感謝任何幫助！

Answer 1

對於首次部署者，這裏是我的問題，我是如何解決他們：

1 RailsInstaller和Heroku的列工具不能完美兼容：如果遇到問題在安裝Heroku工具欄後，我建議您一併刪除railsinstaller和heroku工具欄，然後重新安裝railsinstaller。然後，在您的gem文件中，只需添加gem 'heroku'並運行軟件包安裝。我不需要任何額外的東西來成功部署我的應用程序。 Heroku Toolbelt安裝紅寶石1.9.2 v，併爲您的偏好添加錯誤路徑。你可以選擇手動修復這個PATH到正確的位置，例如）C：RailsInstaller：Ruby1.9.3，但我發現重新安裝所有東西更容易。

2.您必須遷移從sqlite3的到PostgreSQL：遵循this，如果你不知道如何做到這一點。

3.按照Heroku教程最終部署您的應用程序：follow this。如果您收到錯誤消息，提示「對象不存在」，請嘗試運行heroku run rake db:migrate。

祝你好運部署！
