Answer 1

问题似乎是这样的：“ImportError: No module named hellodjango.wsgi”

根据您发布的信息，听起来“hellodjango”不是您的项目和 WSGI 应用程序的名称，因此对 hellodjango.wsgi 的引用失败。

我猜你的项目结构和 wsgi.py 文件中的名称应该是“mysite”。

编辑：您的 procfile 应该调用 .wsgi （这是默认的 django 行为）。

请在评论中最重要的是你用来启动这个项目的项目名称是什么。

Answer 2

更新 procfile，将 mysite.wsgi 替换为您的应用程序的正确名称，它将运行。

您可能是通过教程来到这里的，更改此信息并不明显。

Answer 3

对于我的情况，在 Procfile 中，我将核心文件夹的名称命名为 .wsgi，因此我将其命名为“hellodjango.wsgi”，但随后在 mysite 文件夹中，我在 .wsgi 文件中看到该名称必须是 mysite.wsgi。 所以我回到 Procfile 并将 hellodjango.wsgi 重命名为 mysite.wsgi，然后 Heroku App 完美运行。

Answer 4

检查您在 procfile 中设置的名称

网络：gunicorn“名称”.wsgi --log-file -
