1.使用composer创建laravel项目
composer create-project --prefer-dist laravel/lumen yaomianweiblog
执行次命令行之后会根据你当前的环境下载最为合适的项目结构 OK 将会看到下面的景象

Generating autoload files
到这里就是下载完毕了（这里不得不提composer确实是很好用，但是装composer的过程确实非常蛋疼的！现在都觉得疼！）
2.测试项目运行 在测试之前有两件事很重要
1）修改项目的读写权限
sudo chmod -R 777 yaomianweiblog
2 ) 在public目录中将$app->run() 修改为$app->run($app->request) （目前不知道原因有知道的朋友可以告诉我，感谢！）
做完这两件事之后，在web环境下你就可以访问当前项目首页了 http://localhost/project/yaomianweiblog/public/index.php如果出现 Lumen (5.2.9) (Laravel Components 5.2.*)这句话便说明已经成功了。至此项目初始工作完成第一步！
