附录*Composer
注意:Composer 不是一个包管理器。是的,它涉及 "packages" 和 "libraries",但它在每个项目的基础上进行管理,在你项目的某个目录中(例如vendor)进行安装。默认情况下它不会在全局安装任何东西。因此,这仅仅是一个依赖管理。

安装

  • 局部安装(当前项目安装):
curl -sS https://getcomposer.org/installer | php
使用命令:php composer.phar install
  • 全局安装:
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer
使用命令:composer install

配置中国镜像

查看当前的镜像地址:
$ composer config -g repo.packagist
-----------------------------
{"type":"composer","url":"https?:\/\/packagist.org","allow_ssl_downgrade":true} #当前为国外的源
启动本镜像服务,一下两种配置
  • 系统全局配置
  • 单个项目配置

使用

  • composer初始化
$ composer init
# Package name : cms/test
# Description : test composer
# Author : revin
# Minimum Stability : 忽略,直接确定
# Package Type : project
剩下全部确定
composer.json
{
"name": "cms/test",
"description": "test composer",
"type": "project",
"authors": [
{
"name": "revin",
"email": "[email protected]"
}
],
"require": {}
