The problem is that you're saying "hey bro I heard you liked celery have some celery".
问题是你在说“嘿兄弟，我听说你喜欢芹菜有一些芹菜”。
But really you should be saying, "hey bro I heard you installed celery, lets make a file named something really similar so we don't confuse the hell out of our environment".
但实际上您应该说，“嘿兄弟，我听说您安装了 celery，让我们创建一个名为非常相似的文件，这样我们就不会混淆我们的环境”。
Rename your email/celery.pyfile to email/celery_app.py
将您的email/celery.py文件重命名为email/celery_app.py
Then, when you start your worker, do the following:
然后，当您启动工作程序时，请执行以下操作：
celery -A email worker --app=email.celery_app:app --loglevel=info # etc.
The key is that you need to nothave the file named celery.pyin your file-structure, but if you don't, then you can't rely on celery to find celery, so you have to point it by specifying --app manually.
关键是，你需要不具有命名的文件celery.py在你的文件结构，但如果你不这样做，那么你可以不依靠芹菜找到芹菜，所以你必须手动指定--app点吧。

I was actually having a similar issue, assuming you were following the Next Steps tutorialand all I had to do to resolve the issue was run the worker from the directory above proj, that is, assuming you're currently in the projdirectory run:
我实际上遇到了类似的问题，假设您正在遵循Next Steps 教程，而我解决问题所需要做的就是从proj上面的目录运行工作程序，也就是说，假设您当前在proj目录中运行：
cd ..
celery -A proj worker -l info
It's working for me now.
它现在对我有用。
