我用 django 做了一个网站，我用 celery 做异步任务，当我运行时:
./manage.py runserver
我得到了错误:

ModuleNotFoundError: No module named 'kombu.transport.django'
我知道the django module was definitely removed from the kombu package但是如果我删除 kombu 我会得到第一个错误，我该如何解决这个问题？
我正在使用 django==3.0.3, celery==4.4.1, kombu==4.6.8
最佳答案
你用 celery 4.4.1 要求 kombu<4.7,>=4.6.10，但您将拥有不兼容的 kombu 4.6.8。
请使用:
pip install celery==4.4.6
pip install kombu==4.6.10
如果你想 redis 你应该这个版本
pip install redis==3.2.1
然后你到终端并输入python
关于django with celery raise 运行服务器时没有名为 'kombu' 的模块，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60516587/
