laravel安装ide-helper

1. composer require barryvdh/laravel-ide-helper

如果conposer报错，安装一下openssl试试，注意安装应该是root用户下

   # apt-get install openssl

2. config/app.php里的provider中添加

    Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class,
   

3. 运行以下命令

php artisan clear-compiled
php artisan ide-helper:generate
php artisan optimize

4.如果在项目根目录下有_ide_helper.php就ok了
