为Flask应用程序构建Docker映像失败 [英] Building a docker image for a flask app fails in pip
本文介绍了为Flask应用程序构建Docker映像失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
from alpine:latest
RUN apk add --no-cache python3-dev \
&& pip3 install --upgrade pip
WORKDIR /backend
COPY . /backend
RUN pip --no-cache-dir install -r requirements.txt
EXPOSE 5000
ENTRYPOINT ['python3']
CMD ['app.py']
我有一个类似于上面的简单Dockerfile.
I have a simple Dockerfile that looks like above.
当我执行 docker build -t backend:latest.时，它给了我
ERROR: Command errored out with exit status 1: /usr/bin/python3.7 /usr/lib/python3.7/site-packages/pip install --ignore-installed --no-user --prefix /tmp/pip-build-env-wr55ljb4/overlay --no-warn-script-location --no-binary :none: --only-binary :none: -i https://pypi.org/simple -- 'setuptools>=40.8.0' wheel 'cffi>=1.1; python_implementation != '"'"'PyPy'"'"'' Check the logs for full command output.
The command '/bin/sh -c pip --no-cache-dir install -r requirements.txt' returned a non-zero code: 1
似乎我的点子无法正常工作.有什么想法吗?
Seems like my pip is not working properly. Any thoughts?

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.)
Trying to continue anyway. If you are trying to install CFFI from
a build done in a different context, you can ignore this warning.

推荐答案
我也为此挣扎了一下.我最终用
I struggled with that for a moment as well. I ended up creating my container with
FROM python:3.7-alpine
RUN apk update && apk add gcc libc-dev make git libffi-dev openssl-dev python3-dev libxml2-dev libxslt-dev
无论如何，如果您想使用 alpine:latest ，则可能只需要上面列出的一些os依赖项.
Anyway, if you want to use alpine:latest you probably just need some of the os dependencies I listed above.
