Alias＆＃34; components.HybridAuthIdentity＆＃34;是无效的

Question

我正在关注本教程 http://www.yiiframework.com/wiki/459/integrating-hybridauth-directly-into-yii-without-an-extension/ 进入我自己的应用程序，但我收到一个错误，我花了很多时间来找到我想念的步骤。 这是我的错误。

Alias "components.HybridAuthIdentity" is invalid. Make sure it points to an existing directory or file.

在components目录中，我创建了一个名为HybridAuthIdentity.php的文件

class HybridAuthIdentity extends CUserIdentity{`    
public $hybridAuth;
public $adapter;

public $userProfile;

public $allowedProviders = array('google', 'facebook', 'linkedin', 'yahoo', 'live',);

protected $config;

function __construct() 
{
    $path = Yii::getPathOfAlias('ext.hybridauth');
    require_once $path . '/hybridauth/Hybrid/Auth.php';  

    $this->config = array(
        "base_url" => "touchtalent.dev/login/SocialLogin", 

       "providers" => array(

            "LinkedIn" => array(
               "enabled" => true,
                  "keys" => array ( 
                   "key" => "My key", 
                    "secret" => "my secret id",
               ),
            ),
        ),

        "debug_mode" => false, 


        "debug_file" => "",             
    );

   $this->hybridAuth = new Hybrid_Auth($this->config);
}
}

在我的siteController中，我写道：

Yii::import('components.HybridAuthIdentity');
        $haComp = new HybridAuthIdentity;

        if(!$haComp->validateProviderName($_GET['provider']))
        {

            throw new CHttpException("500", "Invalid action. Please Try again");    
        }
        else
        { 

            $haComp->adaptor = $haComp->hibrydAuth->authenticate($_GET['provider']);
            $haComp->userProfile = $haComp->adaptor->getUserProfile();
            $haComp->login();
            $this->redirect('create');
        }

我该如何解决？感谢所有的目的......
