Heroku 內部服務器錯誤（未找到 python 應用程序）flask

Question

我正在嘗試將 api (Python/Flask) 部署到 Heroku，我的代碼在 [Github][1] 上。

部署后，Heroku 說它成功了（綠色勾號。）但是當我按下視圖時，我會得到這個錯誤：

Internal Server Error

所以我檢查了日志，看看我發現了什么：

 no python application found, check your startup logs for errors

我應該如何解決這個問題？

從部署到錯誤的完整日志：

Answer 1

你的 uwsgi.ini 中有錯別字： modlue = app:app
