使用基本应用程序模板将主题集成到Yii 2时出错

我正在尝试在Yii2中集成一个主题。我把主题放在基本文件夹的主题文件夹里。在config/web.php文件中，我在组件数组下插入了以下代码:

  <?php
$params = require(__DIR__ . '/params.php');
$config = [
    'id' => 'basic',
    'basePath' => dirname(__DIR__),
    'bootstrap' => ['log'],
    'components' => [
        'request' => [
            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
            'cookieValidationKey' => 'bnfhxfasdf7324675@$%fg',
        ],
        'cache' => [
            'class' => 'yii'caching'FileCache',
        ],
        'user' => [
            'identityClass' => 'app'models'User',
            'enableAutoLogin' => true,
        ],
        'errorHandler' => [
            'errorAction' => 'site/error',
        ],
        'mailer' => [
            'class' => 'yii'swiftmailer'Mailer',
            // send all mails to a file by default. You have to set
            // 'useFileTransport' to false and configure a transport
            // for the mailer to send real emails.
            'useFileTransport' => true,
        ],
        'log' => [
            'traceLevel' => YII_DEBUG ? 3 : 0,
            'targets' => [
                [
                    'class' => 'yii'log'FileTarget',
                    'levels' => ['error', 'warning'],
                ],
            ],
        ],
        'db' => require(__DIR__ . '/db.php'),
        'view' => [
            'theme' => [
                'basePath' => '@app/themes/flat',
                'baseUrl' => '@web/themes/flat',
                'pathMap' => [
                    '@app/views' => '@app/themes/flat/views',
                ],
            ],
        ],
    ],
    'params' => $params,
];
if (YII_ENV_DEV) {
    // configuration adjustments for 'dev' environment
    $config['bootstrap'][] = 'debug';
    $config['modules']['debug'] = [
        'class' => 'yii'debug'Module',
    ];
    $config['bootstrap'][] = 'gii';
    $config['modules']['gii'] = [
        'class' => 'yii'gii'Module',
    ];
}
return $config;

但是我得到了错误

Unknown Property – yii'base'UnknownPropertyException
Getting unknown property: yii'web'Application::theme

foreach ($this->_behaviors as $behavior) {
                if ($behavior->canGetProperty($name)) {
                    return $behavior->$name;
                }
            }
        }
        if (method_exists($this, 'set' . $name)) {
            throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
        } else {
            throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
        }
    }

下面是app.log文件中的堆栈跟踪。
