Composer - PHP的依赖管理器

Composer 是一个跟踪本地项目和类库依赖的依赖管理器。

访问 https://getcomposer.org/ 以得到更多信息和文档。

安装 / 使用

1. 下载 composer.phar 该可执行包或使用安装器。

   $ curl -sS https://getcomposer.org/installer | php

2. 创建一个 composer.json 文件来定义你的依赖关系。 注意，这个例子只是一个应用程序的小版本，不是为了发布为包自身。 如要创建类库/包，请阅读 guidelines.

   {
       "require": {
           "monolog/monolog": ">=1.0.0"
       }
   }

3. 运行 Composer: php composer.phar install

4. 在这里浏览更多的包（packages ) Packagist.

从源码安装

要运行测试，或开发 Composer 自身, 你必须使用源码而不是上面介绍的phar文件。

1. 运行 git clone https://github.com/composer/composer.git
2. 下载 composer.phar 可执行文件
3. 运行 Composer 来获取依赖: cd composer && php ../composer.phar install

现在你可以通过执行 bin/composer 脚本来运行 Composer : php /path/to/composer/bin/composer

Composer 全局安装(手动)

由于 Composer 是工作在当前目录下的，还可以把它安装在系统范围。

1. 改变目录 cd /usr/local/bin
2. 获取 Composer curl -sS https://getcomposer.org/installer | php
3. 让phar变为可执行 chmod a+x composer.phar
4. 切换到项目路径 cd /path/to/my/project
5. 使用 Composer 作为你通常使用的 composer.phar install
6. 可选地，你可以把 composer.phar 重命名为 composer 以使它更为方便

Composer 全局安装(via homebrew)

Composer 是 homebrew-php 项目的一部分。

1. Tap the homebrew-php repository into your brew installation if you haven't done yet: brew tap josegonzalez/homebrew-php
2. 运行 brew install josegonzalez/php/composer.
3. 运行 composer 命令来使用Composer。

更新 Composer

执行 php composer.phar self-update 或对应地会更新一个phar，用最新的版本来安装的。
