EAuth扩展Yii2，类nodge \ eauth \ EAuth不存在

Question

我正在尝试在EAuth高级应用程序中使用Yii2扩展名。我通过composer安装它并将其安装在供应商目录下并按照提到的here配置（在common / config / main中配置）。因此，以下是该目录的结构：

root
   vendor
        nodege
            lightopenid
                     provider
                          *files go here*
            yii2-eauth
                     src
                       *files go here*

EAuth.php位于src文件夹下。在控制器中我使用了这个：

use nodge\eauth\EAuth;

当我这样做时：

$eauth = Yii::$app->get('eauth')->getIdentity($serviceName);

我收到以下错误：

  

类nodge \ eauth \ EAuth不存在

我做错了什么？有什么帮助吗？

更新

这是我的配置：

'components' => [
        'cache' => [
            'class' => 'yii\caching\FileCache',
        ],
        'eauth' => [
            'class' => 'nodge\eauth\EAuth',
            'popup' => true, // Use the popup window instead of redirecting.
            'cache' => false, // Cache component name or false to disable cache. Defaults to 'cache' on production environments.
            'cacheExpire' => 0, // Cache lifetime. Defaults to 0 - means unlimited.
            'httpClient' => [
// uncomment this to use streams in safe_mode
//'useStreamsFallback' => true,
            ],
            'services' => [// You can change the providers and their classes.
                'google' => [

                    'clientSecret' => '...',
                    'title' => 'Google',
                ],

                    'clientSecret' => '---',
                ],
                'yahoo' => [
                    'class' => 'nodge\eauth\services\YahooOpenIDService',
                //'realm' => '*.example.org', // your domain, can be with wildcard to authenticate on subdomains.
                ],
        ],
    ],
