解決方法禁用https請求，改用http方式。所以我們在composer.json文件中設置一個本地或全局的composer配置config

方法一：命令行composer config secure-http false。通過命令修改composer.json，效果等同方法二。

方法二：直接改composer.json,給“config”項中加上"secure-http": false 

"config" : {  
        "vendor-dir" : "packages",
        "secure-http": false  
}

 

全局配置（推薦）

composer config -l -g
//切換到國內源  阿里
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
composer config -g --unset repos.packagist
