当我在部署后尝试访问我的应用程序时，会导致H10错误。它似乎在日志中参考了 favicon，并且还说没有安装 Django（我已经pip3 list在我的中运行venv，它似乎在那里，它也在 requirements.txt 中）。

这是日志：

这是我的内容Procfile：

web: python manage.py runserver 0.0.0.0:$PORT

更新 requirements.txt 后，我??遇到了这个问题：

你Procfile的不是一个有效的

你必须改变

web: python manage.py runserver 0.0.0.0:$PORT

到

web: gunicorn your_django_progect_name.wsgi:application --log-file - --log-level debug

请务必将 gunicorn 添加到您的 requirements.txt 档案中。读这个
