无法安装http-cookie gem

Question

我只需要执行一个.rb文件，但它需要很多额外的库。其中一些已经安装，但我在http-cookie上遇到了问题。上面写着：

$>gem install -http-proxy http://myproxy:8888 http-cookie
Temporarily enhancing PATH for MSYS/MINGW...
Building native extensions. This could take a while...
ERROR: Error installing http-cookie:

libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
