错误消息：内部服务器错误Heroku

Question

启动heroku应用程序时，我始终收到此错误 Internal Server Error

然后我去了cmd并做了 heroku logs --tail

，我发现错误是 ModuleNotFoundError: No module named 'main.url' 我的规则

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),

    path('', include("main.url")),
]

然后我转到settings.py，在我的 ROOT_URLCONF = 'mysite.urls'上进行了更改，而不是mysite.urls上，我只放置了urls，但仍然收到相同的错误消息ModuleNotFoundError: No Module named urls

我的settings.py
