fatal: unable to access 'https://github.com/Homebrew/brew/'

fatal: unable to access 'https://github.com/Homebrew/brew/': Could not resolve host: github.com Failed during: git fetch origin master:refs/remotes/origin/master --tags --force

解決方式:

　　1.試着先在終端 ping github.com

 

　　MacBook-Pro:~$ ping github.com 

 PING github.com (13.250.177.223): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 Request timeout for icmp_seq 3 

• 如果 ping 出來是這種結果，就接着看第二步

2. 修改 hosts 配置
   • 在終端中 sudo vi /etc/hosts 打開編輯文件
   • 按 s 進入編輯模式
   • 接着在最下面添加 192.30.253.113 github.com
