如何在Symfony 2.5及最新版本中安装DoctrineExtensions

我需要在qb中使用mysql函数，如DATE（）、NOW（）、FROM_UNIXTIME（）等。我正在阅读本主题。我做到了：

composer require "beberlei/DoctrineExtensions":"dev-master"

doctrine:
    orm:
      auto_generate_proxy_classes: %kernel.debug%
      entity_managers:
        default:
          auto_mapping: true
          dql:
            datetime_functions:
              MONTH: DoctrineExtensions\Query\Mysql\Month
              YEAR: DoctrineExtensions\Query\Mysql\Year

一切恢复正常：

Loading composer repositories with package information
Updating dependencies (including require-dev)
- Installing beberlei/doctrineextensions (dev-master 5e4ec9c)
Cloning 5e4ec9c3ec3434151e1c73144b4ab87ae30aefbc
etc...

当我这么做的时候：

composer require "beberlei/DoctrineExtensions":"dev-master"

doctrine:
    orm:
      auto_generate_proxy_classes: %kernel.debug%
      entity_managers:
        default:
          auto_mapping: true
          dql:
            datetime_functions:
              MONTH: DoctrineExtensions\Query\Mysql\Month
              YEAR: DoctrineExtensions\Query\Mysql\Year

但是！Symfony为我返回此异常：

FileLoaderLoadException: Cannot import resource "/home/domain/www/domain.com/app/config/config.yml" from "/home/domain/www/domain.com/app/config/config_dev.yml". (A YAML file cannot contain tabs as indentation at line 106 (near " dql:").)

对不起，我的英语，但在俄罗斯的互联网部分没有Symfony2框架的普通专家。我希望你的帮助，我的朋友们

从您的错误中：

A YAML file cannot contain tabs as indentation at line 106 (near " dql:")

此文件中有选项卡：

doctrine:
    orm:
      auto_generate_proxy_classes: %kernel.debug%
      entity_managers:
        default:
          auto_mapping: true
          dql:
            datetime_functions:
              MONTH: DoctrineExtensions\Query\Mysql\Month
              YEAR: DoctrineExtensions\Query\Mysql\Year

相反，选项卡创建空间
