php - laravel5.1 安装laravel-debugbar出现问题

Question

composer中设置

"require": {
        "php": ">=5.5.9",
        "laravel/framework": "5.1.*",
        "barryvdh/laravel-ide-helper":"^2.1",
        "barryvdh/laravel-debugbar": "^2.1"
    },

config/app.php中providers设置

/*
*Third-party  Service Providers
*/
Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class,
Barryvdh\Debugbar\ServiceProvider::class,

然后打开首页是空白，不报错

找到问题了，自己写的一个Provider写的有问题，导致不报错了

Answer 1

如果是全新安装的话, 请首先检查storage目录是否有写权限?

话说, provider后面的那个alias是干啥的, 一般安装包时要修改两处. 又有的安装包不需要::class, 这有啥区别?

Answer 2

providers 加 'Barryvdh\Debugbar\ServiceProvider',
aliases 加'Debugbar' => 'Barryvdh\Debugbar\Facade',
