Php Sonata新闻包未安装在Symfony 3.2.9上

我使用Symfony 3.2.9，并尝试安装Sontata新闻包3.0.0。该捆绑包未安装。Symfony 3.2.*有解决方案吗

我的要求（composer.json）：

控制台的一个窗口：

Your requirements could not be resolved to an installable set of     packages.
Problem 1
- sonata-project/news-bundle 3.1.0 requires symfony/framework-bundle    ^2.3 -> satisfiable by symfony/framework-bundle[v2.3.0, v2.x.x ...].

• symfony/frameworkbundle v2.6.9需要symfony/translation~2.6->可被symfony/translation满足[2.6.x-dev，2.7.x-dev，2.8.x-dev，v2.6.0，v2.6.0-BETA1，v2.6.0-BETA2，v2.6.1，v2.x.x，…]但这些与您的需求或最低稳定性相冲突

我应该安装旧symfony版本吗？
