使用Packagist 镜像

建立一个composer.json文件，内容如下：

{    "name": "laravel/laravel",    "description": "The Laravel Framework.",    "keywords": ["framework", "laravel"],    "license": "MIT",    "type": "project",    "require": {
            "php": ">=5.5.9",        "laravel/framework": "5.2.*"    },    "config": {
            "preferred-install": "dist"    },    "repositories": {
            "packagist": {
                "type": "composer",            "url": "https://packagist.phpcomposer.com"        }    }}

通过 Composer 在命令行运行 create-project 命令来安装 Laravel：

composer create-project --prefer-dist laravel/laravel blog

这样就安装了一个blog项目
