ModuleNotFoundError：Dockerized Django 应用程序中没有名为“kafka.vendor.six.moves”的模块

Question

我的 Dockerized Django 应用程序遇到问题。我正在使用以下 Dockerfile 来构建我的应用程序：

FROM python:alpine

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
ENV DJANGO_SUPERUSER_PASSWORD datahub

RUN mkdir app
WORKDIR /app
COPY ./app .
RUN mkdir -p volumes

RUN apk update
RUN apk add --no-cache gcc python3-dev musl-dev mariadb-dev

RUN pip3 install --upgrade pip
RUN pip3 install -r requirements.txt

RUN apk del gcc python3-dev musl-dev

CMD python3 manage.py makemigrations --noinput &&\
    while ! python3 manage.py migrate --noinput; do sleep 1; done && \ 
    python3 manage.py collectstatic --noinput &&\
    python3 manage.py createsuperuser --user datahub  --email admin@localhost --noinput;\
    python3 manage.py runserver 0.0.0.0:8000

在我的requirements.txt 文件中：

kafka-python==2.0.2

当我在 Docker 容器内运行应用程序时，遇到以下错误：

ModuleNotFoundError: No module named 'kafka.vendor.six.moves'

完成错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.12/site-packages/kafka/__init__.py", line 23, in <module>

    from kafka.vendor.six.moves import range
ModuleNotFoundError: No module named 'kafka.vendor.six.moves'

我已经尝试过更新 Kafka 包、检查依赖关系并手动安装六个包。然而，问题仍然存在。任何人都可以提供有关如何解决此错误的见解吗？

预先感谢您的帮助！

这似乎是一个 Python 3.12 问题，我有同样的错误，但在完全不同的上下文中。

代替 FROM python:alpine

我建议你使用 FROM python:3.11

3.12 仍然很新，有许多项目仍在尝试解决问题。
