我在docker镜像中运行alpine并运行ruby代码。这样可以成功安装所有软件包，但是在尝试使用gsl时失败。
这是Dockerfile:
FROM alpine:3.4
RUN apk upgrade --update \
&& apk add libatomic readline readline-dev libxml2 libxml2-dev \
libxslt libxslt-dev zlib-dev zlib ruby yaml \
yaml-dev libffi-dev build-base git nodejs \
ruby-io-console ruby-irb ruby-json ruby-rake \
make gsl gsl-dev \
gcc g++ libffi-dev ruby-dev tzdata
RUN gsl-config --cflags
RUN gem install --no-document nmatrix gsl
ADD scripts/gsl-test.rb test.rb
RUN ruby test.rb
测试文件是:
require 'gsl'
运行docker build。产生以下输出:

任何帮助将不胜感激。
最佳答案
我相信问题是您正在运行gsl版本1.16，然后运行最新的gsl gem(2.1.0.1)。如果您强制gem安装以匹配gsl版本:
gem install --no-document gsl -v 1.16.0.6
它应该出色地工作。
