Appstore 搜索安装iHost
添加github节点，并添加如下映射
140.82.113.4 github.com
199.232.69.194 github.global.ssl.fastly.net
185.199.108.153 assets-cdn.github.com
185.199.109.153 assets-cdn.github.com
185.199.110.153 assets-cdn.github.com
185.199.111.153 assets-cdn.github.com
效果如下
打勾github相关映射

重试多次依然不行
curl: (92) HTTP/2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1)
这个是HTTP/2本身的bug，新版MacOS默认的HTTP连接使用的版本是2
如下重新设置成更稳定的HTTP/1.1版本
git config --global http.version HTTP/1.1
试过之后安装成功，如果怕衍生出其他问题，安装完成之后可以再设置回去（可以不管）
git config --global http.version HTTP/2
成功的画面如下
