显示下列报错

node:events:504
      throw er; // Unhandled 'error' event
      ^

可以将vue.config.js文件中，

devServer: {
    port: port,
    open: open,
    overlay: {
      warnings: false,
      errors: true
    },
    before: require('./mock/mock-server.js')
  },

将其中的：    open:open,

改成：           open:false,

该语句作用是告诉dev-server在服务器启动后打开浏览器，

改完以后就可以通过打开本地端口进行访问了。
