源码安装时候报错，求解决，已经找了一天答案了

[qq_42815714]

PHP Fatal error: Call to a member function prepare() on a non-object in E:\wwwroot\Host805143263\wwwroot\ong\plus\db.php on line 828

然后我找了db.php的828行

826 if( $CONN['duob'] == '1' && $this->bqdoq != $this->dqqz)
827 $this->lianjie($this->DB[$this->bqdoq]);
828 $qq = $this->mysql->prepare($this->sql);

求解决，感激不尽

错误信息是说 $this->mysql 没有 prepare 方法
应该是 $this->mysql 实例化失败，var_dump($this->mysql); 看一下
