如何开启网页底部默认的debug栏目？ [ 未指定版本 ]

我已经按照相关的配置将dubug打开，但是底部调试栏目还是无法出现

if (true) {
    // configuration adjustments for 'dev' environment
    $config['bootstrap'][] = 'debug';
    $config['modules']['debug'] = [
        'class' => 'yii\debug\Module',
        // uncomment the following to add your IP if you are not connecting from localhost.
        'allowedIPs' => ['192.168.10.1','*'],
    ];

    $config['bootstrap'][] = 'gii';
    $config['modules']['gii'] = [
        'class' => 'yii\gii\Module',
        // uncomment the following to add your IP if you are not connecting from localhost.

    ];
    $config['modules']['admin'] = [
        'class' => 'app\modules\admin',
        'layout' => 'layout1'
    ];
}
