1、查ip
进入 ip.chinaz.com ，分别输入github.com 和github.global.ssl.fastly.net
可以查到两个ip
2、修改hosts文件
进入C:\Windows\System32\drivers\etc
在末尾加入ip和网址（两个都加入）并保存
#140.82.113.4 github.com #52.74.223.119 www.github.com #185.31.17.184 github.global.ssl.fastly.net #github #192.30.253.112 github.com #151.101.113.194 github.global.ssl.fastly.net 20.205.243.166 github.com 203.98.7.65 gist.github.com 185.199.108.153 assets-cdn.github.com 185.199.111.133 raw.githubusercontent.com 185.199.110.133 gist.githubusercontent.com 185.199.111.133 cloud.githubusercontent.com #151.101.100.133 camo.githubusercontent.com #151.101.100.133 avatars0.githubusercontent.com #151.101.100.133 avatars1.githubusercontent.com #151.101.100.133 avatars2.githubusercontent.com #151.101.100.133 avatars3.githubusercontent.com #151.101.100.133 avatars4.githubusercontent.com #151.101.100.133 avatars5.githubusercontent.com #151.101.100.133 avatars6.githubusercontent.com #151.101.100.133 avatars7.githubusercontent.com #151.101.100.133 avatars8.githubusercontent.com
