chdir不好使，于是改成下面的绝对路径
执行后，报错
Fatal error: require(): Failed opening required 'D:\Xampp\htdocs\cloud1pei\vendor\autolaod.php' (include_path='D:\Xampp\php\PEAR') in D:\Xampp\htdocs\cloud1pei\bin\saas\createProductIndex.php on line 6

dirname(dirname(__DIR__))是个什么鬼，__DIR__不就能够直接获取路径么
把$v_autoload打印出来不就知道了么
