FATAL Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html

找到关键的部分：

TypeError: Arguments to path.join must be strings
    at Object.posix.join (path.js:488:13)
    at sync (/Users/lfy/ihaowu/node_modules/hexo-qiniu-sync/sync.js:110:26)

查看源代码中的 sync.js，发现其中的 sync() 方法：

1

10
for(file in files) {
       var fname = path.join(local_dir, dir, files[i]); // 这部分出错
       var stat = fs.lstatSync(fname);
       if(stat.isDirectory() == true) {
           sync(path.join(dir, files[i]));
       } else  {
           var name = path.join(dirPrefix, fname.replace(local_dir, '')).replace(/\\/g, '/').replace(/^\//g, '');
           check_upload(fname,name);
       }
   }

上面注释部分似乎是传递的参数类型出错了。

查看了官方最新的代码，发现确实不一样。于是将上面的内容替换成下面：

1
2

4

10
files.forEach(function(file)  {
       var fname = path.join(local_dir + '', dir + '', file + '');
       var stat = fs.lstatSync(fname);
       if(stat.isDirectory() == true) {
           sync(path.join(dir + '', file + ''));
       } else  {
           var name = path.join(dirPrefix, fname.replace(local_dir, '')).replace(/\\/g, '/').replace(/^\//g, '');
           check_upload(fname,name);
       }
   })

问题解决了。
