谁能告诉我执行 mupx deploy时，出现这个错误是什么意思，怎么处理
$ mupx deploy

这是由于NODE版本最新的本身程序有一个小bug
找到这个文件打开
/usr/local/lib/node_modules/mupx/node_modules/archiver/lib/util/index.js
里面内容的32行，内容修改一下
// var buf = new Buffer(size, 'utf8'); 这是原来的，注释掉，换成下面的
var buf = new Buffer(size.toString(), 'utf8');
改好保存后，在运行项目部署命令:mupx deploy
终于成功了吧。。。见提示信息
