Git 错误 fatal: unable to access 'https://github.com/****.git/': Couldn't resolve host

解决办法重新设置和取消代理，前提是你得有代理地址：

# 设置 http 代理
git config --global http.proxy http://127.0.0.1:1080 
# 设置 https 代理
git config --global https.proxy https://127.0.0.1:1080 
# 取消 http 代理
git config --global --unset http.proxy
# 取消 https 代理
git config --global --unset https.proxy

npm config delete proxy

git config --global http.proxy 'socks5://127.0.0.1:1080'
git config --global https.proxy 'socks5://127.0.0.1:1080'
