安装airflow时芹菜和kombu的版本冲突

Question

我正在安装airflow版本1.9.0，并收到以下错误

Traceback (most recent call last):
  ....
bcpmrstbssapp1 airflow: from kombu.entity import Exchange, Queue
airflow: File "/opt/xxx/lib/airflow/kombu/entity.py", line 9, in <module>
airflow: from .serialization import prepare_accept_content
airflow: File "/opt/xxx/lib/airflow/kombu/serialization.py", line 456, in <module>
airflow: for ep, args in entrypoints('kombu.serializers'):  # pragma: no cover
airflow: File "/opt/xxx/lib/airflow/kombu/utils/compat.py", line 89, in entrypoints
airflow: for ep in importlib_metadata.entry_points().get(namespace, [])
....
TypeError: can't intern subclass of string

我使用的是芹菜4.3版，我应该选择特定版本的kombu吗？

Answer 1

将kombu版本修复为4.6.3

pip install kombu==4.6.3
