hexo 的错误

错误如下

Connection to github.com closed by remote host.
fatal: The remote end hung up unexpectedly
error: failed to push some refs to 'git@github.com:xxxxx/xxxxx.github.io.git'
FATAL Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html
Error: Spawn failed
    at ChildProcess.<anonymous> (/home/pi/blog/node_modules/_hexo-util@0.6.3@hexo-util/lib/spawn.js:52:19)
    at ChildProcess.emit (events.js:182:13)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:240:12)

这个错误是因为本地的博客版本与远程的版本不一致，解决方法是删除博客目录下的.deploy_git文件夹，然后克隆远程(也就是将要发布的地址)的仓库到博客目录里面，然后改名字为.deploy_git，另外一个不那么绕的办法是把远端仓库删除，删除本地的.deploy_git，再次发布，不过这样做会导致之前的提交记录丢失。
