在等待连接到supermaket时，Berks安装失败 - Windows 7

Question

当我执行berks安装时，我收到错误

Error retrieving universe from source: https://supermarket.chef.io/

Unable to find a solution for demands: java (0.1.0), tomcat (0.1.0), tar (~> 2.0.0)

虽然我可以通过浏览器连接到https://supermarket.chef.io/，但无法通过cmd.a

ping supermarket.chef.io

这是我的berksfile
