events.js:282
      throw er; // Unhandled 'error' event

Error: getaddrinfo ENOTFOUND x86_64-apple-darwin13.4.0

}
 

 不知道是Vue里什么逻辑，为什么会check hostname = x86_64-apple-darwin13.4.0， 可能是少安装了什么东西吧，知道的大佬给下解决。

搜索了网络，有2种方案

（1）在终端下，执行sudo unset HOST

             (2) 或者编辑，/etc/hosts 文件，推荐这个

127.0.0.1 x86_64-apple-darwin13.4.0 

 

或者

uset HOST

 

就解决了！
