原因是没有安装：Development-Kit
下载地址： https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
安装步骤：

 1.Extract Files <DEVKIT_INSTALL_DIR>
 2.cd <DEVKIT_INSTALL_DIR>
 3.ruby dk.rb init to generate the config.yml
 4.edit the generated config.yml（查看是否包含已安装的ruby，没有则手动添加）
 5.ruby dk.rb review
 6.ruby dk.rb install
 7.gem install rdiscount --platform=ruby  （这一步是测试是否安装成功）

安装成功后在重新在工程目录下Bundle install，例如：C:\Ruby193\work\demo\Bundle install
