composer安装：
laravel默认的命名安装，可能长时间没反应；因为他的镜像在国外所以需要切换镜像：
方法一： 修改 composer 的全局配置文件（推荐方式），然后输入安装命令
composer config -g repo.packagist composer https://packagist.phpcomposer.com // 配置命令
composer create-project laravel/laravel // 安装命令方法二： 修改当前项目的 composer.json 配置文件：
进入你的项目的根目录（也就是 composer.json 文件所在目录），执行如下命令：
composer config repo.packagist composer https://packagist.phpcomposer.com方式三：手动全局模式
新建composer文件夹，然后创建composer.json (推荐方式)
composer/composer.json代码（切换国内镜像）
{"config": {},"repositories": [{"type": "composer", "url": "https://packagist.phpcomposer.com"},{"packagist": false}]
}命令窗口进入到cd: xxx/xx/composer 目录下，运行命令
composer create-project laravel/laravel larave laravel58
// 会在创建一个composer/laravel58文件夹，里面的是laravel文件D:\Learning >composer create-project laravel/laravel l58
