我试图在 Windows 机器上安装 iruby 并且此错误不断出现。目前正在做一些深度学习，我需要使用 sciruby 和 iruby 来执行所需的操作

PS C:\> gem install iruby
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing iruby:
        ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary

need configuration options.

extconf failed, exit code 1

Gem files will remain installed in C:/RailsInstaller/Ruby2.1.0/lib/ruby/gems/2.1.0/gems/rbczmq-1.7.9 for inspection.
Results logged to C:/RailsInstaller/Ruby2.1.0/lib/ruby/gems/2.1.0/extensions/x86-mingw32/2.1.0/rbczmq-1.7.9/gem_make.out

请协助解决此问题

我是python新手，对ruby一无所知，但是我发现ipython notebook太棒了，我想换个内核试试，
所以我刚安装了ruby，结果还是同样的问题，google也没能帮到我，， ，<br> 但是我真的很擅长修补东西，经过一小时的@#$@%&%@%！(@!，我找到了一种方法：
编辑 C:\Ruby22-x64\lib\ruby\gems\2.2.0\gems\rbczmq-1.7.9\ext\rbczmq\extconf.rb
在顶部添加语句 GNU_CHAIN = 1
cd C:\Ruby22-x64\lib\ruby\gems\2.2.0\gems\rbczmq-1.7.9
gem spec ....\cache\rbczmq-1.7.9.gem --ruby > ....\规格\rbczmq-1.7.9.gem.gemspec
gem build ....\specifications\rbczmq-1.7.9.gem.gemspec
现在，gem 列表显示“rbczmq (1.7.9)”

我对ruby一无所知，所以我不知道rbczmq是否真的有效
“iruby notebook”启动成功并添加了新内核“ruby 2.2.2”，但是当我选择它时它也说“内核错误”
Track back说： “操作系统错误：[WinError 193]”

这就是我现在所能提供的全部帮助，所以也许你现在可以弄清楚并告诉我如何让新内核发挥作用
