我想通过使用Symfony 3.4中的compilerPass来覆盖FosUserbundle的控制器（RegistartionController），所以这是我的代码

=== 注册用户编译器密码 ===

<?php

namespace myBundle;

use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;


class RegisterUserCompilerPass extends CompilerPassInterface
{
    public function process(ContainerBuilder $container)
    {
        $container
            ->getDefinition('fos_user.registration.controller')
            ->setClass(MyBundle\Controller\ReplaceRegistrationController::class) ; 
    }
}

这是添加时的文件，将其添加到主包类中

<?php

namespace MyBundle;


use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\Bundle\Bundle;

use MyBundle\DependencyInjection\Compiler\RegisterUserCompilerPass  ; 


// use Crypto\UserBundle\Manager\ReplaceRegistration ; 

class CryptoUserBundle extends Bundle
{
    public function build(ContainerBuilder $container)
    {
     parent::build($container);
       $container->addCompilerPass(new RegisterUserCompilerPass() );
    }

}

当访问我的注册路径时我得到

编译错误：类 MyBundle\DependencyInjection\Compiler\RegisterUserCompilerPass 无法从接口 Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface 扩展
