最近在git clone使用用户名密码的时候遇到这个问题。解决方案如下:
git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080
change proxyuser to your proxy user
change proxypwd to your proxy password
change proxy.server.com to the URL of your proxy server
change 8080 to the proxy port configured on your proxy server
