windows環境下 composer 的安裝與使用

一、下載穩定版本 composer.phar 1.10.8 至 php 安裝目錄（即與 php.ini 同級）

二、在 composer.phar 同目錄下 新建 composer.bat 文件，用記事本打開並輸入

@php "%~dp0composer.phar" %*

三、配置 composer  !!! 因爲安裝了 php5.6 以及 php7.3 ，須指定 php.exe，如下操做皆在 php7.3 下運行  !!!

# 查看 全局配置
./php.exe ./composer.phar config -g -l

# 重置 源
./php.exe ./composer.phar config -g --unset repositories.packagist

# 設置 阿里雲源
./php.exe ./composer.phar config -g repositories.packagist composer https://mirrors.aliyun.com/composer/

# 禁用 https 鏈接
./php.exe ./composer.phar config -g secure-http false

# 運行 診斷命令
./php.exe ./composer.phar diagnose
