django celery错误＆＃34;应用尚未加载＆＃34;我尝试过的所有推荐修复都失败了 - 我相信我的某些设置配置不正确

Question

我的目标是使用芹菜每天使用芹菜在我的网站上自动运行脚本。我按照Django here的第一步说明进行操作。配置完所有设置后，我使用celery -A project worker --loglevel=info，服务器似乎开始正常。当我尝试导入任务app时，它无法找到该模块，它表示它不存在，但如果我明确调用folder.tasks它就可以工作。如果我拨打function.delay()，我会收到以下错误：

  

提升AppRegistryNotReady（＆＃34;应用尚未加载。＆＃34;）
    django.core.exceptions.AppRegistryNotReady：尚未加载应用。

我在celery.py中使用app.autodiscover_tasks()在我的任务模块中找到@shared_task 我做了一些搜索，并尝试添加使用Django-Q的建议。在我把它放在已安装的应用程序的底部并尝试python manage.py migrate芹菜之后，我得到了与之前相同的AppRegistryNotReady错误，但是当我尝试启动芹菜时。我尝试按照某人的建议在我的settings.py中添加import django | django.setup()。我该如何解决这个问题？这是追溯

非常感谢您的帮助！另外，像我一样解释5.对所有这些来说还是很新的。谢谢！
