国内网络环境被墙，会出现连接错误，如下：

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    Errno::ECONNABORTED: An established connection was aborted by the software in your host machine. - SSL_connect (https://api.rubygems.org
/quick/Marshal.4.8/haml-4.0.6.gemspec.rz)

淘宝提供了淘宝提供了RubyGems的国内镜像站点，解决办法是：

C:\Users\dul>gem sources --remove https://rubygems.org/
https://rubygems.org/ removed from sources

C:\Users\dul>gem sources -a http://ruby.taobao.org/
source http://ruby.taobao.org/ already present in the cache

C:\Users\dul>gem sources -l
*** CURRENT SOURCES ***

http://ruby.taobao.org/

请确保只有 ruby.taobao.org
