原因
由於某些原因導致GitHub的raw.githubusercontent.com域名解析被污染了，或者被牆啦。。
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.
解決方法
sudo vim /etc/hosts # 綁定host 199.232.28.133 raw.githubusercontent.com
