我试图用这个Dockerfile安装seaborn：
FROM alpine:latest
RUN apk add --update python py-pip python-dev
RUN pip install seaborn
CMD python
我得到的错误与numpy和scipy有关(seaborn要求).它始于：
/tmp/easy_install-nvj61E/numpy-1.11.1/setup.py:327: UserWarning:
Unrecognized setuptools command,proceeding with generating Cython
sources and expanding templates
最后以
File “numpy/core/setup.py”,line 654,in get_mathlib_info
RuntimeError: Broken toolchain: cannot link a simple C program
Command “python setup.py egg_info” Failed with error code 1 in /tmp/pip-build-DZ4cXr/scipy/
The command ‘/bin/sh -c pip install seaborn’ returned a non-zero code: 1
知道如何解决这个问题吗？
但是你会看到你会遇到一个新的错误,因为numpy,matplotlip和scipy有几个依赖关系.你还需要安装gfortran,musl-dev,freetype-dev等.
这是一个基于你的初始版本的Dockerfile,它将安装这些依赖项以及seaborn：
FROM alpine:latest
# install dependencies
# the lapack package is only in the community repository
RUN echo "http://dl-4.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories
RUN apk --update add --no-cache \
lapack-dev \
gcc \
freetype-dev
RUN apk add python py-pip python-dev
# Install dependencies
RUN apk add --no-cache --virtual .build-deps \
gfortran \
musl-dev \
g++
RUN ln -s /usr/include/locale.h /usr/include/xlocale.h
RUN pip install seaborn
# removing dependencies
RUN apk del .build-deps
CMD python
您会注意到我正在使用apk-del .build-deps删除依赖项以限制图像的大小(http://www.sandtable.com/reduce-docker-image-sizes-using-alpine/).
我个人也必须安装ca证书,但似乎你没有这个问题.
注意：你也可以从python：2.7-alpine图像构建你的图像,以避免安装python和pip自己.
