如何在Windows上为ruby安装PCAP

这一定是一个相对较新的问题，但我仍然被卡住了。我知道有一个简单的解决办法。我在谷歌上搜索了一下，但找不到确切的答案。这是我得到的错误

C:\Ruby193\include\ruby-1.9.1\i386-mingw32>gem install pcap
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing pcap:
        ERROR: Failed to build gem native extension.

        C:/Ruby193/bin/ruby.exe extconf.rb
checking for socket() in -lsocket... no
checking for gethostbyname() in -lxnet... no
checking for hstrerror()... no
checking for pcap.h... no
*** extconf.rb failed ***
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.

显然，我缺少一些库，但我不知道如何获取这些库，也不知道在尝试安装pcap时它们应该位于何处

最终的解决方案是不使用pcap rub，这似乎已经过时了

我试过PCAP rub，但仍然遇到问题。你可以沿着Jonm最终帮助我站起来跑步的地方走。

这是一段半长的路。我怎样才能连接它？它确实提到了像。。。。
