Question

我很难让它工作，我收到以下错误：

无法找到模板“KnpMenuBundle :: menu.html.twig”（查看：D：\ Server \ htdocs \ symfonudem \ app / Resources / views，D：\ Server \ htdocs \ symfonudem \ vendor \ symfony \ symfony \ SRC \的Symfony \桥\枝条/资源/视图/表格）。

以下是我的Builder类代码。

<?php
namespace AppBundle\Menu;

use Knp\Menu\FactoryInterface;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerAwareTrait;

class Builder
{
  use ContainerAwareTrait;

  public function mainMenu(FactoryInterface $factory, array $options)
  {
    $menu = $factory->createItem('root');

        $menu->addChild('Home', ['route' =>  'homepage']);


        return $menu;
  }
}

 ?>

以下是base.html.twig

的代码

    <head>
        <meta charset="UTF-8" />
        <title>{% block title %}Welcome!{% endblock %}</title>
