Yii2框架继承bootstrap4方法

1.安装yiisoft/yii2-bootstrap4

composer require yiisoft/yii2-bootstrap4

注意此时安装到vendor/npm-asset/目录下

2.替换框架引用的yiisoft/yii2-bootstrap

//资源设置
'assetManager'=>[
     'bundles'=>[
                //替换成bootstrap4
                'yii\bootstrap\BootstrapAsset'=>[
                    'sourcePath' => '@npm/bootstrap/dist',
                    'css'=>['css/bootstrap.min.css'],
                    'js'=>['js/bootstrap.bundle.min.js'],
                ],
     ],
],
