我正在尝试从我的 python 应用程序中构建 docker 图像。但是当我将“snowflake-connector-python”添加到 pip requirements.txt 文件时，docker build 失败了。
要求.txt:-
boto3
pycryptodome
snowflake-connector-python
Dockerfile:-
FROM python:alpine3.6
RUN python --version
COPY . /sample-app
WORKDIR /sample-app
RUN python -m pip install --upgrade pip
RUN pip install --upgrade setuptools
RUN pip --version
RUN pip install -r requirements.txt
CMD [ "python", "runner.py" ]
CLI docker 构建:-
docker build -t sample-app:1.0 .
错误 :-
Step 8/9 : RUN pip install -r requirements.txt

Complete output from command python setup.py egg_info:
No working compiler found, or bogus compiler options passed to
the compiler from Python's standard "distutils" module. See
the error messages above. Likely, the problem is not related
to CFFI but generic to the setup.py of any Python package that
tries to compile C code. (Hints: on OS/X 10.8, for errors about
-mno-fused-madd see http://stackoverflow.com/questions/22313407/
Otherwise, see https://wiki.python.org/moin/CompLangPython or
the IRC channel #python on irc.freenode.net.)
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-7dudc372/cffi/
The command '/bin/sh -c pip install -r requirements.txt' returned a non-zero code: 1
可能是什么问题 ？我在这里错过了什么吗？

最佳答案
alpine linux 非常小，他们必须删除所有内容，因此您必须自己安装。某些 pip 包需要在您的机器上编译/构建，但 alpine 缺少这些依赖项，因此请安装它们，然后进行 pip 安装，然后删除它们，因为不再需要它们，您将减小图像大小。
雪花docs还说你必须安装libffi-dev和 openssl-dev
FROM python:alpine3.6
COPY . /sample-app
WORKDIR /sample-app
RUN apk add --update --no-cache --virtual build-deps gcc python3-dev musl-dev libc-dev linux-headers libxslt-dev libxml2-dev \
&& apk add libffi-dev openssl-dev \
&& pip install --upgrade pip setuptools \
&& pip install -r requirements.txt \
&& apk del build-deps
CMD [ "python", "runner.py" ]
关于python-3.x - 当 pip 要求中包含雪花依赖项时，docker build 失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51626987/
