我想在我的symfony应用程序中安装composer.phar我从https://github.com/composer/composer开始下载调用。
但是当我运行命令时：
php composer.phar install
我在我的consol中有这个：
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].
任何帮助请!!
