YII框架模块实现

Question

YII框架模块建好，配置也复制好，就是无法访问，目前崩溃中

'modules' => [
        'article' => [
            'class' => 'app\modules\article\Article',
        ],
    ],

复制到web.php $config中，一切都是照着敲的，不明白就是无法访问

<?php

namespace app\modules\article\controllers;

use yii\web\Controller;

class DefaultController extends Controller
{
    public function actionIndex()
    {
        //return $this->render('index');
    }
}
