• 问题出现：原本是在mac正常使用的， 切换到windows时突然出现这个报错

fatal: in unpopulated submodule '.deploy_git'
FATAL {
  err: Error: Spawn failed
      at ChildProcess.<anonymous> (D:\workplace\blog\node_modules\hexo-util\lib\spawn.js:51:21)
      at ChildProcess.emit (events.js:376:20)
      at ChildProcess.cp.emit (D:\workplace\blog\node_modules\cross-spawn\lib\enoent.js:34:29)
      at Process.ChildProcess._handle.onexit (internal/child_process.js:277:12) {
    code: 128
  }
}

• 解决： 把根目录下的 .deploy_git 目录删除即可
