【问题描述】：
我终于让我的 Heroku 应用程序至少在本地工作了！但是，当我尝试在线打开它时，它会崩溃并出现以下错误：
> 2021-10-29T13:16:54.435118+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of

我不确定该怎么做，但是当我在本地运行应用程序时，它说：

它说我有 20 个未应用的迁移，这就是它不能在线工作的原因吗？在进行迁移然后迁移时，它只是说没有要应用的迁移。
大多数人似乎建议对 Procfile 进行一些更改，但我不太了解 Procfile，也不知道要写什么或为什么要写它。无论如何，我没有找到任何似乎适用于我的应用程序的东西，其中大部分似乎与 JSON 有关。
【问题讨论】：
-
推送您的迁移，然后尝试。您需要在本地文件夹中推送迁移
-
我运行了“heroku run python manage.py migrate”并且它迁移了。我仍然崩溃，但同样的错误。
