我使用最新版本的 Silex（不是 Phar 版本）。我在实现表单服务提供者和翻译提供者时遇到问题，我收到以下错误：

“致命错误：第 47 行的 D:\xampp\htdocs\mytest\vendor\symfony\translation\Symfony\Component\Translation\Loader\XliffFileLoader.php 中找不到类 'Symfony\Component\Config\Resource\FileResource'”

如果我禁用此行，表单会显示并且一切正常（翻译除外）。我什至收到消息，可以从德语表格的一个选项中进行选择。

$app->register(new Silex\Provider\ValidatorServiceProvider());

请给我一个提示如何解决这个问题。请在下面查看我的代码和我的 composer.json 文件：

应用程序.php：

<?php
$app = new Silex\Application();
$app['debug'] = true;

use Silex\Provider\FormServiceProvider;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;

$app->register(new Silex\Provider\FormServiceProvider());
$app->register(new Silex\Provider\TranslationServiceProvider(), array(
    'locale' => 'de',
    'fallback_locale' => 'en',
));
$app->register(new Silex\Provider\ValidatorServiceProvider());
$app->register(new Silex\Provider\TwigServiceProvider(), array(
    'twig.path' => __DIR__.'/../views',
));

// Sample from silex-homepage
$app->match('/form', function (Request $request) use ($app) {
    // some default data for when the form is displayed the first time
    $data = array(
        'name' => 'Your name',
        'email' => 'Your email',
    );

    $form = $app['form.factory']->createBuilder('form', $data)
        ->add('name')
        ->add('email')
        ->add('gender', 'choice', array(
            'choices' => array(1 => 'male', 2 => 'female'),
            'expanded' => true,
        ))
        ->getForm();

    if ('POST' == $request->getMethod()) {
        $form->bindRequest($request);

        if ($form->isValid()) {
            $data = $form->getData();

            // do something with the data

            // redirect somewhere
            return $app->redirect('...');
        }
    }

    // display the form
    return $app['twig']->render('test.html', array('form' => $form->createView()));
});

return $app;
?>
