【问题描述】：

我正在尝试设置从 github 存储库克隆的 Symfony 项目，但在安装依赖项时遇到问题。

当我运行 composer install 时，结果如下：

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Installation request for doctrine/mongodb 1.0.0-BETA1 -> satisfiable by doctrine/mongodb[1.0.0-BETA1].
- doctrine/mongodb 1.0.0-BETA1 requires ext-mongo * -> the requested php extension mongo is missing from your system.
Problem 2
- Installation request for symfony/icu 1.1.x-dev -> satisfiable by symfony/icu[1.1.x-dev].
- symfony/icu 1.1.x-dev requires lib-icu >=3.8 -> the requested linked library icu has the wrong version installed or is missing from your system, make sure to have the extension providing it.
Problem 3
- symfony/icu 1.1.x-dev requires lib-icu >=3.8 -> the requested linked library icu has the wrong version installed or is missing from your system, make sure to have the extension providing it.
- symfony/symfony 2.3.x-dev requires symfony/icu ~1.0 -> satisfiable by symfony/icu[1.1.x-dev].
- Installation request for symfony/symfony 2.3.x-dev -> satisfiable by symfony/symfony[2.3.x-dev].

这是 composer.json

【问题讨论】：

错误消息是不言自明的。你有什么问题？

您解决问题的第一步是here

【参考方案1】：

作曲家明确表示您的系统缺少ext-mongo、lib-icu 和依赖于第二个的symfony/icu。

对于 ext-mongo，如果 extension=mongo.so 已被评论，请检查您的 php.ini，如果是，请取消评论。

对于 lib-icu，您缺少 php 的 intl extension 进行设置，您可以按照以下答案进行操作：Problems with lib-icu dependency when installing Symfony 2.3.x via Composer
