Laravel学习1-创建项目

设备：MAC

• 进入web服务的项目目录下
  我的web服务项目路径是用户路径下的 Workespaces/php

    cd Workespaces/php    pwd    /Users/nht/Workespaces/php

• 使用composer创建laravel项目

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

以上代码使用最新的laravel版本创建名为laravelapp 的项目

创建指定laravel版本的项目

composer create-project laravel/laravel=5.4.* laravel --prefer-dist  

注：通过 Composer 或者 Laravel 安装器安装的话，该 key 的值已经通过 php artisan key:generate 命令生成好了

以下是使用composer创建项目自动执行的过程
主要是一些依赖的下载，并自动使用了如下命令

@php -r “file_exists(‘.env’) || copy(‘.env.example’, ‘.env’);”
Illuminate\Foundation\ComposerScripts::postAutoloadDump
@php artisan package:discover
@php artisan key:generate
