Symfont 2.8中的错误-无法重新声明类Symfony \\ Component \\ DependencyInjection \\ ContainerAwareInterface

Question

您可以在这个问题上帮助我吗？我将Symfont 2.8与EasyAdminBundle一起使用 。 我曾被本手册用来安装-symfony2-admin-panel-in-30-seconds 。

管理面板工作正常，但是当我尝试创建我的（非管理员）类时，出现错误： 无法在/ var / www / html / Legendcorp / app / cache / dev /中重新声明类Symfony \\ Component \\ DependencyInjection \\ ContainerAwareInterface 6568行的classes.php

例如：我在/src/AppBundle/Controller/APIController.php中创建了该类

namespace AppBundle\Controller;
use JavierEguiluz\Bundle\EasyAdminBundle\Controller\AdminController as BaseAdminController;
use Symfony\Component\HttpFoundation\Request;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;



class FormController extends BaseAdminController{
    /**
     * @Route("/form/save", name="save")
     */
    public function formAction(Request $request){

    }

}

但是当我尝试申请该课程时，出现错误。 -

• Fatal error: Cannot redeclare class Symfony\\Component\\DependencyInjection\\ContainerAwareInterface in /var/www/html/Legendcorp/app/cache/dev/classes.php on line 6568

如果我清除了缓存（ rm -rf app / cache / * ），它将起作用， 但前提是您不与管理面板联系。

这是我的composer.json文件：

拜托，你能帮我吗？

您关注的博客文章非常好，但是对于诸如安装捆绑软件之类的事情，我始终建议您遵循官方文档。 在这种情况下： 第1章。从EasyAdmin的文档进行安装 。

关于ContainerAwareInterface错误，我想说它与包无关。 我们不会在任何地方使用该接口，也不会使用ContainerAware类。 如果删除捆绑包，Symfony应用程序是否可以正常运行？
