Cannot extend from interface CompilerPassInterface in Symfony 3.4

Question

I want to override the controller (RegistartionController) of FosUserbundle by the using of compilerPass in Symfony 3.4 so this is my code

=== RegisterUserCompilerPass ===

<?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) ; 
    }
}

and this is file when add add it to the main bundle class

<?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() );
    }

}

when access to my register path i get

Compile Error: Class MyBundle\DependencyInjection\Compiler\RegisterUserCompilerPass cannot extend from interface Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface

class RegisterUserCompilerPass extends CompilerPassInterface

should be

class RegisterUserCompilerPass implements CompilerPassInterface

See PHP can't extend from interface?
