By default, when you install yii2, a file AppAsset.php will be created at: /path-to-application/assets/AppAssset.php .

If, for some reason, it didn't, I would strongly recommend reinstall the framework, just in case of anything else is missing. Be sure you are following the tutorial

IF you just need this file, you can find its content here in the docs :

<?php

namespace app\assets;

use yii\web\AssetBundle;

class AppAsset extends AssetBundle
{
    public $basePath = '@webroot';
    public $baseUrl = '@web';
    public $css = [
        'css/site.css',
    ];
    public $js = [
    ];
    public $depends = [
        'yii\web\YiiAsset',
        'yii\bootstrap\BootstrapAsset',
    ];
}

问题是因为我的gitignore文件，我已经将资产目录放入gitignore文件中，因此，当我从项目中克隆克隆时，找不到某些类。
