似乎，

$PORT

有时会有所不同。然而，heroku配置说明如下：

(.env) $ heroku config
=== my-app Config Vars
PORT: 33507

为什么不工作？

默认情况下，开发服务器仅绑定到

localhost

，您必须指定要绑定到任何IP：

web: python subfolder/manage.py runserver 0.0.0.0:$PORT

但是在生产环境中运行dev服务器是一个非常糟糕的主意。您确实应该使用

gunicorn

或其他适当的服务器来部署您的项目：

web: gunicorn subfolder/yourproject.wsgi

如果需要更多指导，请按照上的步骤操作。

使用Django开发服务器而不是像gunicorn这样的服务器有什么原因吗？在heroku上运行gunicorn是个坏主意：
