django 1.11 与 celery 4.0 和 djcelery 兼容性问题

Question

我目前使用的是 django 1.11，出于兼容性原因，我不得不使用旧版本的 celery (3.1)。

我想升级到celery 4.0，因为我们应用程序的另一部分需要更高版本的celery。

是否有兼容的 celery、django-celery 和 django 1.11 的组合？文档说 celery 4.0 从 1.8 开始兼容所有版本的 django，但事实似乎并非如此。

例如当我使用时出现错误：

python manage.py makemigrations <appname>

这是我收到的错误消息：

Traceback (most recent call last):
File "manage.py", line 10, in <module>
execute_from_command_line(sys.argv)
File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 363, in execute_from_command_line

File "/usr/local/lib/python2.7/dist-packages/djcelery/models.py", line 16, in <module>
from . import managers
File "/usr/local/lib/python2.7/dist-packages/djcelery/managers.py", line 18, in <module>
from celery.utils.timeutils import maybe_timedelta
ImportError: No module named timeutils

如果我恢复到 celery 3.1，就可以了。

您正在使用 django-celery，一个 no longer required since celery 3.1

的库

Previous versions of Celery required a separate library to work with Django, but since 3.1 this is no longer the case. Django is supported out of the box now ...

从 INSTALLED_APPS 中删除 djcelery，按照链接文档查看是否还有其他需要更新的内容，它应该可以工作。
