Question

我正在尝试在我的Ubuntu 14.04计算机上安装SciRuby但安装失败。我也有一个开放的github issue问题但在安装过程中没有成功。通过查看错误，我确信存在一些C / C ++编译问题。任何帮助将不胜感激

似乎sciruby-full需要许多本地库。运行步骤..

RUN apt-get update   
RUN apt-get install -y build-essential python3 python3-dev python3-pip ruby ruby-dev libzmq3 libzmq3-dev gnuplot-nox libgsl0-dev libtool autoconf automake zlib1g-dev libsqlite3-dev libmagick++-dev imagemagick libatlas-base-dev    
RUN apt-get clean &&      
ln -s /usr/bin/libtoolize /usr/bin/libtool
RUN pip3 install "ipython[notebook]"
RUN gem install --no-rdoc --no-ri sciruby-full && iruby register

未能安装sciruby
