Mac终端无法访问 https://github.com

dgq@dgqdeMacBook-Pro ~ % curl -v https://github.com
* Host github.com:443 was resolved.

curl: (28) Failed to connect to github.com port 443 after 75034 ms: Couldn't connect to server

在这里插入图片描述

解决办法：点击复制终端代理命令

dgq@dgqdeMacBook-Pro ~ % export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890

此时再次访问就成功了！！！

dgq@dgqdeMacBook-Pro ~ % curl -v https://github.com
