我正在使用Symfony2,我正在将我的网络部署到CentOs6服务器.我得到了这个例外

FatalErrorException: Error: Call to undefined function Doctrine\ORM\Mapping\Driver\simplexml_load_file() in vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/Driver/XmlDriver.php line 736

我错过了什么 ？谢谢

我使用的是 Symfony 2.3.*，当我使用 LiipImagineBundle 时，我在 app/logs/dev.log 中收到此错误。

request.CRITICAL: Uncaught PHP Exception Imagine\Exception\InvalidArgumentException: "png_compression_level option should be an integer from 0 to 9" at /vendor/imagine/imagine/lib/Imagine/Gd/Image.php line 535 {"exception":"[object] (Imagine\\Exception\\InvalidArgumentException: png_compression_level option should be an integer from 0 to 9 at /vendor/imagine/imagine/lib/Imagine/Gd/Image.php:535)"} []

有什么解决办法吗？谢谢

这是我的配置

liip_imagine:
    resolvers:
       default:
          web_path: ~
    filter_sets:
        cache: ~
        standard:
            quality: 200
            filters:
                thumbnail: { size: [400, 300], mode: outbound }
