大家好！我正在用 Python 3.12.0 编写一个小型应用程序，并使用 Redis 作为 Celery 的消息代理（DB=0）。我还使用Redis来存储缓存（DB=1）。在开发过程中，Redis是在docker中启动的。一切都很好。现在我决定将所有内容打包到 docker-compose 中。然后问题开始了......我的 Dockerfile：
FROM python:3.12.0
LABEL authors="agrytsai"
ENV PYTHONUNBUFFERED=1
RUN pip install poetry
WORKDIR /app
COPY pyproject.toml poetry.lock ./
RUN poetry install --no-dev --no-root
COPY . .
Docker 组合：
services:
app:
build:
context: .
env_file:
- .env
command: >
sh -c "poetry run python manage.py wait_for_db &&
poetry run python manage.py migrate &&
poetry run celery -A MyProject worker --pool=solo --loglevel=INFO &&
poetry run python main.py"
depends_on:
- redis
redis:
image: redis:alpine
restart: on-failure
env_file:
- .env
ports:
- "6379:6379"
volumes:
- $REDISDATA
- redis_data:/data
command: redis-server /usr/local/etc/redis/redis_cache.conf
volumes:
redis_data:
当我尝试执行时docker-compose up --build，Redis正常启动，python manage.py wait_for_db并且python manage.py migrate是一样的。然后我收到错误：

该错误表明版本不兼容。我已经安装了redis = "^5.0.8"，文档说明：
**注意：** redis-py 5.0 将是支持 Python 3.7 的最后一个 redis-py 版本，因为它已达到生命周期。 redis-py 5.1 将支持 Python 3.8+。那些。 Python 3.12.0 + redis 5.0.8 完全兼容。
可能是什么问题？我已经尝试解决这个问题近一周了，但仍然无法解决（
我找到了解决方案 - 问题出在虚拟环境上。我删除了旧的，创建了一个新的，重新安装了所有的软件包，它就工作了。
