英文:
using mysqlclient in docker
问题
我在努力安装mysqlclient在Docker上。
我在互联网上看到了很多不同的建议，比如：
- 运行 apt-get install -y libmysqlclient-dev
- 运行 apt-get update && apt-get install -y default-libmysqlclient-dev
- 运行 apt-get install mysql-community-client
我都尝试过了。
以下是我的Dockerfile（我分别尝试了1、2和3）：
FROM python:3.9
RUN apt-get install -y libmysqlclient-dev ## 尝试1
RUN apt-get update && apt-get install -y default-libmysqlclient-dev # 尝试2
RUN apt-get install mysql-community-client ## 尝试3
RUN pip install asgiref boto3 botocore Django Jinja2 jmespath MarkupSafe numpy pandas python-dateutil pytz PyYAML render s3transfer six sqlparse tzdata urllib3 asyncio websockets channels mysqlclient mysql-connector-python bcrypt python-dotenv cryptography mysql
RUN pip install daphne
COPY . /frontend
WORKDIR /frontend
CMD ["python", "manage.py", "runserver", "0.0.0.0:8001"]
尝试1的输出：
ERROR [3/7] RUN apt-get install -y libmysqlclient-dev 1.1s

------

尝试2在构建时成功，但在启动时失败。
尝试3的输出：

因此，由于以上方法都没有成功，我还尝试进入Docker容器手动安装它。

它无法导入到Python中，但声称已经安装了。请问我该如何在Docker中让mysqlclient正常工作？

可能pip install缺少其他一些包。<br>
您尝试过从mysqlclient页面运行以下命令吗？<br> sudo apt-get install python3-dev default-libmysqlclient-dev build-essential
在您的Dockerfile中尝试：
FROM python:3.9
RUN apt-get update -y
RUN apt-get install -y python3-dev build-essential
RUN apt-get install -y default-libmysqlclient-dev
英文:
Maybe the pip install is missing some other packages.<br>
Have you tried the command from the mysqlclient-page?<br> sudo apt-get install python3-dev default-libmysqlclient-dev build-essential
In your Dockerfile try:
FROM python:3.9
RUN apt-get update -y
RUN apt-get install -y python3-dev build-essential
RUN apt-get install -y default-libmysqlclient-dev
