【问题描述】：

我正在使用带有 celery 4.2.1 和 django2 的 django-celery-beat。

起初它运行良好，但在 gunicorn 日志中显示一段时间后出现以下错误

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/gunicorn/arbiter.py", line 515, in spawn_worker
    worker.init_process()

    return _bootstrap._gcd_import(name[level:], package, level)
  File "/usr/local/lib/python3.5/dist-packages/django_celery_beat/models.py", line 8, in <module>
    from celery.five import python_2_unicode_compatible
ImportError: cannot import name 'python_2_unicode_compatible'

这是一种非常奇怪的行为，我找不到更多信息。

标签： django gunicorn django-celery supervisord celerybeat

【解决方案1】：

从 4.4.7 升级到 5.0.5 后发生这种情况

    from django_celery_beat.models import PeriodicTask, IntervalSchedule, CrontabSchedule


File "/home/someUser/PycharmProjects/some-project/venv/lib/python3.6/site-packages/django_celery_beat/models.py", line 8, in <module>
    from celery.five import python_2_unicode_compatible
ModuleNotFoundError: No module named 'celery.five'

降级回 celery==4.4.7 没问题

包裹python_2_unicode_compatible好像错位了？

【解决方案2】：

最后，我为 celery 和 gunicorn 使用了不同的版本，修复了所有这些都按预期工作。

【解决方案3】：

替换

from celery.five import python_2_unicode_compatible

通过

from django.utils.encoding import python_2_unicode_compatible

可能会解决您的问题。
