Can'；在Alpine Linux上不需要ruby gsl

我在docker映像中运行alpine并运行ruby代码。这将成功安装所有软件包，但在尝试要求gsl时失败

以下是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

测试文件为：

require 'gsl'

运行docker构建。生成以下输出：

非常感谢您的帮助。

我相信问题在于您正在运行gsl 1.16版，然后运行最新的gsl gem（2.1.0.1）。如果强制gem安装与gsl版本匹配：

gem install --no-document gsl -v 1.16.0.6

它应该工作出色
