Php 安装Symfony2 CMF时出现无效配置异常

刚刚进入Symfony2，我想使用CMF包

我在这里遵循食谱：

跑步时

composer.phar update

我得到这个错误：

    [Symfony\Component\Config\Definition\Exception\InvalidConfigurationException]                                                                                
  When the dynamic router is enabled, you need to either enable one of the persistence layers or set the cmf_routing.dynamic.route_provider_service_id option  

路由\提供商\服务\ id的正确设置是什么？我找不到关于这个的任何文档

config.yml

# CMF config
cmf_routing:
chain:
    routers_by_id:
        cmf_routing.dynamic_router: 200
        router.default: 100
dynamic:
    enabled: true
    route_provider_service_id: ~
sonata_block:
    default_contexts: [cms]

这是我的composer.json文件：

这里介绍了cmf路由

这里还有更多的细节（我只是与路由提供者进一步澄清了这一点，因为我意识到它不是很明确）

路由的配置参考如下：
不知道我在动态配置中使用的设置，我仍然会遇到错误：当启用动态路由器时，您需要启用其中一个持久层或设置cmf_routing.Dynamic.route_provider_service_id选项。最好在github上打开一个问题，因为我在此处没有收到注释通知。如果您设置了持久化orm或PHTo为true或配置了route_provider_service_id选项（阅读链接的文档以了解需要在那里执行的操作），消息应该会消失。
