user模組下RegistorController.class.php 和RegistorModel.class.php

RegistorController.class.php 程式碼

namespace User\Controller;
use Think\Controller;
use User\Model\RegistorModel;

class RegistorController extends Controller
{

    public function test(){
        new RegistorModel();
//        D('Registor');
    }
}

RegistorModel.class.php

namespace User\Model;
use Think\Model;

class RegistorModel extends Model
{

}

訪問地址test()方法,提示無法載入資料庫驅動: ThinkDbDriver\
就這麼幾行程式碼,整整一上午,tp和核心程式碼我又重下了一遍.能排除的我都排除了,鬱悶死了
tp的詳細報錯訊息

无法加载数据库驱动: Think\Db\Driver\
