Sometimes downloading things on github in China is very slow... One of the solutions is to set up a proxy for git
//查看当前设置
git config --global http.proxy
// 设置当前代理使用http或者socks 如果使用shadowsocks，那么就是socks5://127.0.0.1:1080
git config --global http.proxy 'http://127.0.0.1:1080'
git config --global https.proxy 'http://127.0.0.1:1080'
git config --global http.proxy 'socks5://127.0.0.1:1080'
git config --global https.proxy 'socks5://127.0.0.1:1080' /
// 删除代理
git config --global --unset http.proxy
git config --global --unset https.proxy
PS: global表示全局设置
