Rbczmq error while installing iruby
I am trying to install iruby on a windows machine and this error keeps popping up. I am currently doing deep learning and I need to use sciruby and iruby to do the required steps.
PS C:\> gem install iruby
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...

I'm new to python and don't know anything about ruby, but I think the ipython notebook is so great that I want to try it for a different kernel,
so I just installed ruby โโand ended up with the same problem and google didn't help me,
but I'm really good at things after one hour @ # $ @ % &% @%! (@ !, I found a way:
C: \ Ruby22-x64 \ lib \ ruby โโ\ gems \ 2.2.0 \ gems \ rbczmq-1.7.9 \ ext \ rbczmq \ extconf.rb
add the GNU_CHAIN โโ= 1 statement at the top
cd C: \ Ruby22-x64 \ lib \ ruby โโ\ gems \ 2.2.0 \ gems \ rbczmq-1.7.9
gem spec .... \ cache \ rbczmq-1.7.9.gem --ruby> ... . \ spec \ rbczmq-1.7.9.gem.gemspec
gem build .... \ spec \ rbczmq-1.7.9.gem.gemspec
now the list of gems displays "rbczmq (1.7.9)"
I didn't know anything about ruby, so I don't know if rbczmq actually works or not. "iruby notebook" starts succ and new kernel "ruby 2.2.2" is added, but it also says "kernel error" when I select it
Track Back says "OSError: [WinError 193]"
Now I can help, so maybe now you can figure it out and tell me how to get the new kernel to do the trick
