github进不去

1.首先排除网络问题

2.打开host：C:\Windows\System32\drivers\etc
在最后加上添加
192.30.253.112 github.com
192.30.253.119 gist.github.com
151.101.100.133 assets-cdn.github.com
151.101.100.133 raw.githubusercontent.com
151.101.100.133 gist.githubusercontent.com
151.101.100.133 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
添加完之后，保存退出。然后关掉浏览器，重新打开即可。输入github网址，即可进入。

3.如果此时还是不能打开github页面，在原hosts文件末尾加上如下：

192.30.255.112 github.com git
185.31.16.184 github.global.ssl.fastly.net
