无法在Windows上安装Unicorn

Question

我无法在本地主机上安装Unicorn（操作系统 - Windows 8）。

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

    E:/software/Ruby200-x64/bin/ruby.exe extconf.rb

Could not create Makefile due to some reason, probably lack of necessary 
libraries and/or headers. Check the mkmf.log file for more details. You may 
need configuration options. 

Provided configuration options: 
     --with-opt-dir 
     --without-opt-dir 
     --with-opt-include 
     --without-opt-include=${opt-dir}/include 
     --with-opt-lib 
     --without-opt-lib=${opt-dir}/lib 
     --with-make-prog 
     --without-make-prog 
     --srcdir=. 
     --curdir 
     --ruby=E:/software/Ruby200-x64/bin/ruby 
     --with-rtlib 
     --without-rtlib 
     --with-nsllib 
     --without-nsllib 
     --with-socketlib 
     --without-socketlib 


Gem files will remain installed in E:/software/Ruby200-x64/lib/ruby/gems/2.0.0/gems/kgio-2.9.2 for inspection. 
Results logged to E:/software/Ruby200-x64/lib/ruby/gems/2.0.0/gems/kgio-2.9.2/ext/kgio/gem_make.out 

为什么？我究竟做错了什么？我该如何解决它？

我使用Ruby on Rails 4.1.4 btw。

在此先感谢。

Unicorn does not have native Windows support。
