Django: ImportError: cannot import name 'Celery' from 'celery'
Django: ImportError: cannot import name 'Celery' from 'celery'
所以我已经安装了 celery 并在我的项目目录中 settings.py 旁边得到了文件 celery_tasks_settings.py。我得到的是一种避免与包本身发生冲突的方法。
我也做了
find -name '*celery*.pyc'
作为查找可能已生成的任何 celery.pyc 文件的方法 before.The 结果：
/__pycache__/celery_tasks.cpython-38.pyc
/__pycache__/celery_tasks_settings.cpython-38.pyc
不幸的是，我仍然遇到同样的错误：
from celery import Celery
ImportError: cannot import name 'Celery' from 'celery'
我是不是做错了什么？
PS：我也继续尝试添加：
from __future__ import absolute_import, unicode_literals
给我的 celery_tasks_settings.py
我的错误仍然没有改变。

这可能是一个循环导入问题。看起来您正在尝试在 celery_task_settings.py 中导入 Celery，这导致循环导入导致导入错误。
我将 importlib-metadata 从 0.19 版升级到 1.5.0 版，它为我完全解决了这个问题。
作为参考，我有一个几乎相同的完整回溯：
