过去几天我一直在试着部署但就是没能成功在heroku上，它说应用程序已部署，但当我进入日志时，我看到了错误。我尝试打开应用程序（例如，管理页面），我得到了应用程序错误。我尝试在导入任何其他内容之前调用get_asgi_application，但没有工作。以下是我收到的错误：错误

File "/app/.heroku/python/lib/python3.9/site-packages/django/apps/registry.py", line 136, in check_apps_ready
    raise AppRegistryNotReady("Apps aren't loaded yet.")
 django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.
Process exited with status 1
 State changed from starting to crashed

at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=myappname.herokuapp.com request_id=18f76666-adff-40f8-83ae-55df56d78208 fwd="24.150.189.187" dyno= connect= service= status=503 bytes= protocol=https

我的asgi文件：

import os
from django.core.asgi import get_asgi_application
import django
#from channels.auth import AuthMiddlewareStack


#from channels.security.websocket import AllowedHostsOriginValidator
from channels.routing import ProtocolTypeRouter, URLRouter

#from .settings import ALLOWED_HOSTS
from myappnameapp.routing import *

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myappname.settings')
django.setup()

#from django.urls import path

django_asgi_app = get_asgi_application()
from myappname.auth_middleware import TokenAuthMiddleware

application = ProtocolTypeRouter({
    # (http->django views is added by default)
    "http": django_asgi_app,
    'websocket': TokenAuthMiddleware(
        URLRouter(
            websocket_urlpatterns
        )
    ),
})

我的程序文件：

release: python manage.py migrate
web: daphne myappname.asgi:application --port $PORT --bind 0.0.0.0 -v2
worker: python manage.py runworker channel_layer -v2

设置文件：

FIREBASE_APP = initialize_app()

我试过添加. import django，然后调用django.setup（）。然而同样的错误不断出现。任何帮助都将不胜感激
解决了！
根据Iain Shelvington在评论中的解决方案！！
