使用代理时网页访问正常，git无法clone

明明已经使用了vpn，命令行还git clone一直被拒绝

fatal: unable to access 'https://github.com/pytorch/vision/': Failed to connect to github.com port 443 after 21206 ms: Couldn't connect to server

首先，检测ping是否成功

$ ping github.com

ping github不成功，国内网站成功

这应该是设置代理的问题
“7890”为代理的端口号

git终端输入：

 git config --global http.proxy '127.0.0.1:7890'
 
 git config --global https.proxy '127.0.0.1:7890'
