首先，访问https://www.ipaddress.com/，搜索以下域名对应的ip地址
github.com assets-cdn.github.com github.global.ssl.fastly.net
然后，修改hosts文件
# GitHub Start 140.82.114.4 github.com 185.199.109.153 assets-cdn.github.com 185.199.111.153 assets-cdn.github.com 185.199.108.153 assets-cdn.github.com 185.199.110.153 assets-cdn.github.com 199.232.5.194 github.global.ssl.fastly.net # GitHub End
最后，刷新dns
ipconfig /flushdns
