安装symfony2 cmf编写器问题

Question

对于Symfony来说，这是一个非常新的概念，我想让CMF正常工作，但是我在使用composer安装它时遇到了问题

在终端运行代码时，我得到了这个

警告：锁文件不是最新的composer.json.您可能会得到过时的依赖项。运行更新以更新它们。您的需求无法解析为一组可安装的包。

问题1
-symfony/icu 1.2的安装请求。x-dev-

问题2
-symfony/icu 1.2。x-dev需要lib-icu

按照我的作曲家的要求。json看起来像这样。。。

我跑了

composer.phar update

没有错误，但其他问题对我来说有点神秘

任何帮助都将不胜感激。。。
