Question

我从Symfony2开始时出错。

YamlFileLoader.php第356行中的InvalidArgumentException：没有扩展程序可以加载＆＃34;服务＆＃34; （在/Users/jm/Documents/Websites/www.brsymfony.dev/src/CalcBundle/DependencyInjection/../Resources/config/services.yml）。寻找命名空间＆＃34;服务＆＃34;，找不到

我的services.yml看起来像是有正确的空格：

services:
    Calculator:
        class: CalcBundle\Services\Calculator
        arguments:
            - @doctrine.orm.default_entity_manager
    ListOperations:
        class: CalcBundle\Services\ListOperations
        arguments:
            - @doctrine.orm.default_entity_manager

任何人都可以帮助我吗？

是的，我在DependencyInjection文件夹中的CalcExtension.php上有这段代码：

<?php

namespace CalcBundle\DependencyInjection;

use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\ContainerBuilder;

/**
 * Class AppExtension
 */

class CalcExtension extends Extension
{
    /**
     * Loads a specific configuration.
     *
     * @param array            $config    An array of configuration values
     * @param ContainerBuilder $container A ContainerBuilder instance
     *
     * @throws \InvalidArgumentException When provided tag is not defined in this extension
     *
     * @api
     */
    public function load(array $config, ContainerBuilder $container)
    {
        $loader = new YamlFileLoader(
            $container,
            new FileLocator(__DIR__ . '/../Resources/config')
        );
        $loader->load('services.yml');
    }
}

提前致谢：）

您是否在DependencyInjection文件夹上创建了扩展程序？应该是CalcBundle / DependencyInjection / CalcExtension.php

您的文档包含示例 http://symfony.com/doc/current/cookbook/bundles/extension.html

public function load(array $configs, ContainerBuilder $container)
{
    $configuration = new Configuration();
    $config = $this->processConfiguration($configuration, $configs);

    $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
    $loader->load('services.yml');
}

services.yml应位于CalcBundle / Resources / config / services.yml

上

要小心，因为示例正在将参数和服务一起创建到config.yml中，你必须根据你的情况调整它（services.yml和parameters.yml分开，我建议你的方式）

Symfony2错误查找命名空间＆＃34;服务＆＃34;，找不到
