我使用django 1.10.5和芹菜4.0.2。我有这样的结构。
-proj
-application
__init__.py
celery.py
celery_conf.py
settings.py
tasks.py
urls.py
wsgi.py
-extuser (application with extended UserModel)
-pages
-migrations
-templates
__init__.py
admin.py
apps.py
forms.py
models.py
tasks.py
tests.py
views.py
我的任务是使用包含扩展用户模型的文件中的模型。如果我尝试使用此命令运行芹菜：
celery -A application worker -l INFO -B
然后我看到了这个错误：

文件页面/ tasks.py看起来像这样：
from __future__ import absolute_import, unicode_literals
from application.celery import app
from extuser.models import UserLinksArchive
@app.task
def link_destroy_task(link_id):
link = UserLinksArchive.objects.get(id=link_id)
link.delete()
另外，如果我将UserLinksArchive导入本地，那么芹菜就会启动，但是当它运行async_task的时候我得到了同样的错误。 如您所见，问题可能在于使用AbstractBaseUser导入。但我不知道如何解决这个问题。 也许，extuser / models.py代码会有所帮助。

如果您在tasks.py的方法中导入UserLinksArchive，则可以修复此问题。
@app.task
def link_destroy_task(link_id):
from extuser.models import UserLinksArchive
link = UserLinksArchive.objects.get(id=link_id)
link.delete()

我已将导入放入任务中，但我写的问题仍然存在。
所以，经过几个小时探索这个问题，我找到了原因。在我的情况下，问题出在我的要求中的一个包中。我甚至不知道它是如何出现的，真的，不知道（也许会知道是否会出现问题）。这是我的requirements.txt
amqp==2.1.4
anyjson==0.3.3
billiard==3.5.0.2
celery==4.0.2

我发现我甚至无法从其他应用导入包。 Runserver倒下了，出现了这样的错误：
/env/local/lib/python2.7/site-packages/printer.py", line 8
print("\t",end='')
^
SyntaxError: invalid syntax
我的python版本是2.7，这不起作用。 这是我第一次感受到difference between 2.7 and 3.x print
最后，我刚刚删除了这个包。
到目前为止飞行是正常的。
