ModuleNotFoundError("'kafka' 不是有效名称。您是说 aiokafka，kafka 之一吗？")

Question

我正在使用 Celery 和 Kafka 运行一些作业，以便将数据推送到 Kafka。我也用浮士德来连接工人。但不幸的是，为了运行管道，我在运行宁 faust -A project.streams.app worker -l info 之后出现错误。不知道有没有人能帮帮我。

我不知道 Faust 出了什么问题，但我运行 pip install faust 偶然发现它解决了问题。

ModuleNotFoundError("'kafka' 不是有效名称。您是说 aiokafka，kafka 之一吗？")

ModuleNotFoundError("'kafka' is not a valid name. Did you mean one of aiokafka, kafka?")

python

django

django-celery

apache-kafka
