Php 所需的软件包无法'；在任何版本symfony2中都找不到

嘿
我在生成Symfony2管理面板时遇到问题，我的Symfony版本是2.5，以下是我在安装Sonata管理包时遇到的问题

---

我希望您遵循Sonata官方管理网站上的安装说明：

将此添加到composer.json：

---

“sonata project/admin bundle”：“2.3.*@dev”

在我的文件中写下这条语句后，我运行composer.phar安装，仍然是它报告的问题！您是否删除了“sonata project/doctrine phpcr admin bundle”：“1.1.*”？不，我没有发布您的composer.json如何在注释中附加我的文件？您可以粘贴您的composer.json文件吗？ Problem 1 - Installation request for symfony-cmf/standard-edition 1.1.x-dev -> satisfi able by symfony-cmf/standard-edition[1.1.x-dev]. - symfony-cmf/standard-edition 1.1.x-dev requires sonata-project/doctrine-ph pcr-admin-bundle 1.1.* -> no matching package found. Potential causes: -A typo in the package name -The package is not available in a stable-enough version according to your min imum-stability setting
