PHP管理依赖(dependency)关系工具 Composer 安装与使用
php  /  管理员 发布于 6年前   124
PHP Composer 安装 系统需求: Composer 需要PHP5.3.2+ 以上的环境来运行。有几个敏感的PHP设置和编译标志也是必需的,但安装程序会发出警告当存在任何不兼容的情况。 比如PHP的扩展的要求是,安装或重新编译php without Cdisable-phar 为了从源地址安装软件包,而不是简单的压缩文件包,您将需要安装软件包的版本控制工具,比如git、svn或hg等。 Composer 是兼容多平台的,其运行适用于Windows,Linux和OSX。 安装失败的错误消息: 我的本地默认开发环境是PHP 5.2.9,当我尝试在PHP 5.2.9上安装时,提示版本过低,需要升级到PHP 5.3.2 或者更高的版本。 于是我下载XAMPP 1.7.7 usb lite 版本。 XAMPP 1.7.7 下的PHP环境是5.3.8。确认我的PHP环境大于等于PHP5.3.2后。 PHP 5.3 安装 Composer 注意: 我关闭了XAMPP 1.7.7 Apache的SSL模块,所以Composer提示我警告,为了安全因素建议我开启SSL模块。不开启也不影响使用。 安装完成后,检查安装版本。 检查PHP Composer命令: 这样我们在PHP5.3环境下的Composer已经安装完成。 类似的方法我们也可以安装PHP 5.4的环境上。 PHP 5.4 安装 Composer 下载XAMPP 1.8.1 usb lite 版本,将得到PHP5.4.7环境。 确定版本高于PHP 5.3.2 后,开始安装: 安装完成后,检查安装版本。 这样,PHP 5.4 环境下的Composer也安装成功了。 PHP Composer 使用 这里我只简单演示使用PHP Composer安装Symfony框架。 首先大概讲解一下命令的标准格式: 第一个参数PHP为本地PHP开发环境,指向PHP运行命令。 根据上述我们在PHP5.4环境下安装的Composer,我们的安装命令为: 安装结果: 从命令行结果,我们看到了整个Symfony框架的安装过程与结果。 PHP Composer 定义依赖关系 Composer在使用时会自动寻找composer.json这个文件。 composer.json将用来定义整个项目的依赖包。例如: 依赖包简单的说明,我们的项目需要一些从1.2开始的任何版本的monolog/monolog包。 Composer是PHP中的一个依赖关系管理工具。通过Composer我们可以在发布软件时节省大量的文件数目和控制依赖包的版本。 PHP Composer 项目 Composer 项目官方:http://getcomposer.org Composer Github项目:https://github.com/composer/composer PHP Composer软件包列表:https://packagist.org/curl -sS https://getcomposer.org/installer | PHP #!/usr/bin/env php some settings on your machine make Composer unable to work properly. Make sure that you fix the issues listed below and run this script again:The phar extension is missing. Install it or recompile php without Cdisable-pharYour PHP (5.2.9) is too old, you must upgrade to PHP 5.3.2 or higher.

安装时的参数 | PHP,一定要更改为真实的PHP环境路径,比如 | E:\USB\xampp_177\php\php.exe
使用Composer为PHP路径 + 命令,在我们安装的环境中,使用方法为:E:\USB\xampp_177\php/php.exe composer.phar 命令。
我安装的环境是在Windows下,如果在Linux下,而PHP 5.3 环境也不在默认PHP命令下时,应该采用 | /usr/php/53/usr/bin/php,例如:curl -sS https://getcomposer.org/installer | /usr/php/53/usr/bin/php
