我想在我下载调用后的symfony应用程序中安装composer.phar

但当我运行命令时:

 php composer.phar install
我的控制台里有这个:

 Problem 1

-Installation request for symfony/icu v1.2.1 -> satisfiable by symfony/icu[v1.2.1]

-symfony/icu v1.2.1 requires lib-icu >=4.4 -> the requested linked library icu has the extension providing it.

Problem 2

-symfony/symfony v2.5.0 requires symfony/icu ~1.0 -> satisfiable by symfony/icu[v1.2.1].

-symfony/symfony v2.5.0 requires symfony/icu ~1.0 -> satisfiable by symfony/icu[v1.2.1].

-symfony/icu v1.2.1 requires lib-icu >=4.4 -> the requested linked  library icu has the wrong version installed or is missing from your system, make sure have the extension providing it.

- Installation request for symfony/symfony v2.5.0 -> satisfiable by symfony/symfony[v2.5.0].

请帮忙

您需要安装/更新。

我的composer.json中有这样的代码:“php”:“>=5.3.3”,“symfony/symfony”:“2.5.*”,“条令/orm”:“~2.2,>=2.2.3”,“条令/条令包”:“~1.2”,“细枝/扩展”:“~1.0”,“symfony/assetic包”:“~2.3”,“symfony/swiftmailer包”:“~2.3”,“symfony/monolog捆绑包”:“~2.4”,“sensio/distribution捆绑包”:“~3.0”,“sensio/framework额外捆绑包”:“~3.0”,“IncenteV/composer参数处理程序”:“~2.0”,“friendsofsymfony/user捆绑包”:“~2”。0@dev“您使用什么样的系统:windows还是linux?请检查,如果您想使用symfony 2.5,您必须安装/更新php intl扩展,它可能会帮助您。我现在使用symfony 2.5,我会使用FosuserBundle,但我在composer.phar中遇到问题,是否有其他方法安装此捆绑包而不使用composer?”?
