我刚刚添加了一个mysql连接，但脚本仍然失败。错误如下，相关的js低于该值。

TypeError: 'undefined' is not a function (evaluating 'loadClass.bind(null, 'Types')')

TypeError: '[object Object]' is not a constructor (evaluating 'new Connection({config: new ConnectionConfig(config)})')

  app/node_modules/mysql/index.js:12 in createConnection

app.js

var Q = require("q");
var page = require('webpage').create();
//var crypto = require('./node_modules/crypto/sha1.js');
var mysql = require('mysql');

var connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'shaun',
  password : 'somepassword',
  database : 'db'
});

connection.connect();
