望君多指点!

Answer 1

应该是你的Github SSH配置问题

可以通过

$ ssh -vT git@github.com 

来判断是否配置成功 如果显示

Hello xxxx! You ve successfully authenticated, but GitHub does not provide shell access.

表示成功

具体如何配置SSH 请看
https://help.github.com/articles/generating-ssh-keys

Answer 2

应该是ssh网关的问题，github的ssh请求有时候会被封掉，不知道为什么
用https替换ssh就可以了
