Procfile.txt

web: gunicorn app:run

run.py是我的文件名，如下所示：-

from gumshuda import app

if __name__ == "__main__":
    app.run(debug=True)

---

如果需要，一定要询问更多信息。

我通过将文件从

run.py

重命名为

app.py

但根据@saransh singh在评论中的说法 我们也可以通过在procfile中进行更改来解决这个问题 从

web:gunicorn应用程序：运行

到
web:gunicorn run:app
程序文件内容应该是
web:gunicorn run:app
，因为
run.py
是您的输入文件。Okhay，谢谢你，我通过将我的文件从
run.py
重命名为
app.py
