当我尝试运行daphne -p 8001 messanger.asgi:application时，我得到以下错误：django.core.exceptions.AppRegistryNotReady:应用程序尚未加载。如果我在没有daphne的情况下运行服务器，我会得到这个错误：侦听失败：第127章不能听0.0.1：8000：[错误48]地址已在使用中。
这是我的设置。py：

INSTALLED_APPS = [
    "channels",
    "chat",
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
    'django_extensions',
]

ASGI_APPLICATION = "messanger.asgi.application"

CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [os.environ.get("REDIS_URL", "redis_url")],
        },
