linux composer 安装与应用

linux下composer安装与简单应用
-------------------------------------安装------------------------------------
//下载composer
curl -sS https://getcomposer.org/installer | php

//将composer.phar文件移动到bin目录以便全局使用composer命令

mv composer.phar /usr/local/bin/composer

//切换国内源

composer config -g repo.packagist composer https://packagist.phpcomposer.com

------------------------------------简单应用----------------------------------
//安装thinkphp5

composer create-project topthink/think whatever_you_like_name --prefer-dist

//更新项目

切换到项目文件夹中(与composer.json文件同级目录) 
composer  update 

//安装拓展 (dependency manager for PHP)

例如,安装支付宝 微信集成接口

composer require riverslei/payment

执行完了就安装了,查看composer.json文件,require部分多了 "riverslei/payment": "~2.0"

安装位置一般在项目扩展文件夹,如:TP5中的vendor.
