不能在 Alpine Linux 上要求 ruby gsl

Question

在 docker 图片和运行 ruby 代码中我是运行高山。这成功安装了所有软件包，但是当我尝试 require 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

测试文件为：

require 'gsl'

运行 docker 构建。产生以下输出：

我认为问题是您运行 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

它应该能很好地工作。
