使用以下 docker 文件，
FROM python:3.9-slim-buster
WORKDIR /python-docker
COPY requirements.txt requirements.txt
RUN python3 -m pip install --upgrade pip
RUN pip3 install -r requirements.txt
COPY . .
EXPOSE 5000
CMD [ "python3", "-m" , "flask", "run", "--host=0.0.0.0"]
需求文件如下，
boto3==1.21.32
Flask==2.2.2
Flask_Cors==3.0.10
hvac==1.0.2
PyJWT==2.6.0
PyMySQL==0.10.1
zenpy==2.0.24
gunicorn==20.1.0
pandas==1.4.2
当我尝试使用以下命令构建多弧 docker 文件时，
docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 -t name/flask-docker:latest --push .它显示以下输出：

Dockerfile:9

7 | RUN python3 -m pip install --upgrade pip

9 | >>> RUN pip3 install -r requirements.txt
正如上面的问题所说，这不是 pip 的问题，无法准确判断是否是任何底层包的问题？
注意：我尝试从需求文件中删除 pandas 并且它正在工作，但我需要它，因为我有一个基于此的导入。
好的，只需尝试一个一个地安装软件包，或者您可以删除每个软件包后的版本，这样它就会自动调整 就像这样
boto3
Flask
Flask_Cors
hvac
PyJWT
PyMySQL
zenpy
gunicorn
pandas
#I think it will work fine
