[shrimpma]

问题：
CentOs ,命令行模式，使用hexo搭建博客，使用github pages ，部署时出现一下错误：
# hexo g -d

error: The requested URL returned error: 403 Forbidden while accessing http://github.com/shrimpma/shrimpma.github.io.git/info/refs

fatal: HTTP request failed
FATAL Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html
Error: error: The requested URL returned error: 403 Forbidden while accessing http://github.com/shrimpma/shrimpma.github.io.git/info/refs

fatal: HTTP request failed

备注：github 帐号正确，可以pull ,push 代码
