Question

对Symfony来说很新，我想让CMF工作但我在使用composer安装它时遇到问题

在终端中运行代码时，我得到了这个

警告：锁定文件与composer.json中的最新更改不是最新的。您可能会过时的依赖项。运行更新以更新它们。   您的要求无法解析为可安装的软件包。
     问题1        - symfony / icu 1.2.x-dev的安装请求 - ＆gt;可以通过symfony / icu [1.2.x-dev]来满足        - symfony / icu 1.2.x-dev需要lib-icu＆gt; = 4.4 - ＆gt;请求的链接库icu安装了错误的版本或缺少版本   你的系统，请确保提供它的扩展。

问题2
        - symfony / icu 1.2.x-dev需要lib-icu＆gt; = 4.4 - ＆gt;请求的链接库icu安装了错误的版本或缺少版本    你的系统，请确保提供它的扩展。
        - symfony / symfony 2.3.x-dev需要symfony / icu~1.0 - ＆gt; symfony / icu [1.2.x-dev]可以满足。         - symfony / symfony 2.3.x-dev的安装请求 - ＆gt; symfony / symfony [2.3.x-dev]可以满足。

根据要求，我的composer.json看起来像这样......

        "branch-alias": {
            "dev-master": "2.3-dev"
        }
    }
}

我跑了

composer.phar update

没有错误，但其他问题对我来说有点神秘

任何帮助将不胜感激......
