Symfony3 您请求了一个不存在的服务“validator.builder”，同时添加 FOSUserBundle

Question

我有 Symfony 微内核，我正在尝试添加 FOSUserBundle。通过本指南安装后https://symfony.com/doc/master/bundles/FOSUserBundle/index.html我收到了“validor.builder”错误

Fatal error: Uncaught Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "validator.builder". in /var/www/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/ContainerBuilder.php on line 754

调用栈

/app_dev.php:0 Symfony\Component\HttpKernel\Kernel->handle() .../app_dev.php:9 Symfony\Component\HttpKernel\Kernel->boot() .../Kernel.php:166 Symfony\ Component\HttpKernel\Kernel->initializeContainer() .../Kernel.php:117 Symfony\Component\DependencyInjection\ContainerBuilder->compile() .../Kernel.php:477 Symfony\Component\DependencyInjection\Compiler\Compiler- >compile( ) .../ContainerBuilder.php:528 FOS\UserBundle\DependencyInjection\Compiler\ValidationPass->process() .../Compiler.php:104 Symfony\Component\DependencyInjection\ContainerBuilder->getDefinition() .. ./ValidationPass.php:41

看来symfony 找不到服务validator.builder，它与symfony FrameworkBundle 一起使用。有没有人有建议问题出在哪里以及缺少什么？谢谢！

            $bundles[] = new \Symfony\Bundle\DebugBundle\DebugBundle();
        }

        return $bundles;
    }

    protected function configureContainer(ContainerBuilder $c, LoaderInterface $loader)

        // configure WebProfilerBundle only if the bundle is enabled

                'intercept_redirects' => false,
            ));

            $routes->import('@WebProfilerBundle/Resources/config/routing/profiler.xml', '/_profiler');
        }
    }

    // optional, to use the standard Symfony cache directory
    public function getCacheDir()

        return __DIR__ . '/cache/' .$this->getEnvironment();
    }

    // optional, to use the standard Symfony logs directory

    }
}

修复您报告的错误很容易。只需添加：

services:
  validator.builder:
    class: Symfony\Component\Config\Definition\Builder\ValidationBuilder

到您的 services.yml

...然而，这并不能解决我的所有问题，并且会导致更多问题，因为缺少所有来自 FOS 用户包的身份验证服务。我花了一段时间试图添加这些服务定义，但我认为内心深处有些问题。FOSUserBundle 还没有支持 Symfony 3 的标记版本。您可以尝试dev-master在作曲家中使用它，看看它是如何工作的，但它并没有为我修复它。

我的建议是首先尝试使用默认的 Symfony3 应用程序（不使用微内核），如果仍然失败，请决定您想要更多的 Symfony3 或 FOSUserBundle。
