原因

由于某些原因导致GitHub的raw.githubusercontent.com域名解析被污染了，或者被墙啦。。

Currently only limited information about the hostname raw.githubuercontent.com or the domain githubuercontent.com are available. Please check back later to see if we have gathered extensive statistics about the raw.Githubuercontent.com website then.

解决方法

sudo vim /etc/hosts
# 绑定host
199.232.28.133
