Php 如何通过主题覆盖视图？（yii2）

我需要重写一个视图文件，比如“pathMap”=>['@dektrium/user/views'=>'@app/views/site']，我遵循了手册（），但无论我做什么，我看到的都是旧视图。baseUrl或basePath可能有问题，但我不确定该怎么办

frontend/config/main.php：

'components' => [
'request' => [
            'csrfParam' => '_csrf-frontend',
            'baseUrl' => '/',
        ],
// .................
'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
                '/' => 'site/index',
                '<action:\w+>' => 'site/<action>',
            ],
        ],
'view' => [
       'class' => 'yii\web\View',
            'theme' => [
                //'basePath' => '@app/themes/basic',
                //'baseUrl' => '@app/views/site',
                'pathMap' => [
                    '@dektrium/user/views' => '@app/views/site'
                ]
            ]
        ]
//.................
]

'modules' => [
'user' => [
            'class' => 'dektrium\user\Module',
            'admins' => ['admin'],
            'modelMap' => [
                'User' => 'common\models\User',
            ],
]

我在地址上打开页面，比如mydomain.test/user/register（以防万一） 我还尝试将“视图”部分放在common/config/main.php和模块的组件中。尝试创建主题文件夹并在其中放置新视图，但似乎没有任何效果

好的，我终于修复了它

'view' => [
            'class' => 'yii\web\View',
            'theme' => [
                'basePath' => '@frontend/views/site',
                'baseUrl' => '@frontend/views/site',
                'pathMap' => [
                    '@dektrium/user/views/registration' => '@frontend/views/site',
                ]
            ]
        ]

好的，我终于修好了

'view' => [
            'class' => 'yii\web\View',
            'theme' => [
                'basePath' => '@frontend/views/site',
                'baseUrl' => '@frontend/views/site',
                'pathMap' => [
                    '@dektrium/user/views/registration' => '@frontend/views/site',
                ]
            ]
        ]
