* This class will be used to build menu for admin panel based on the user role
*/
class AdminPanelMenu {
static function menu(Request $request){
$user = $request->user();
if($user->hasRole['super_admin'])
return self::superAdmin();
if($user->hasRole['admin'])
return self::admin();
if($user->hasRole['user'])
return self::user();
return [];
}
private static function superAdmin()
{
return [
'MAIN NAVIGATION',
];
}
private static function admin()
{
return [
'MAIN NAVIGATION',
];
}
private static function user()
{
return [
'MAIN NAVIGATION',
];
}
}
What am I doing wrong here?

You need to create a new app container and then bind it to the Facade.
您需要创建一个新的应用程序容器，然后将其绑定到 Facade。
use \Illuminate\Container\Container as Container;
use \Illuminate\Support\Facades\Facade as Facade;
/**
* Setup a new app instance container
*
* @var Illuminate\Container\Container
*/
$app = new Container();
$app->singleton('app', 'Illuminate\Container\Container');
/**
* Set $app as FacadeApplication handler
*/
Facade::setFacadeApplication($app);
in lumen: bootstrap/app.php
在流明：bootstrap/app.php
$app->withFacades();
Good luck!
祝你好运！

I know this is old but maybe it will help someone. I ran into this problem after I was fiddling with my app/config.php file. I added some options and accidentally put a semi-colon instead of a comma after it. I had:
我知道这很旧，但也许它会帮助某人。在我摆弄我的 app/config.php 文件后，我遇到了这个问题。我添加了一些选项，但不小心在它后面放了一个分号而不是逗号。我有：
'vapid_public_key' => env('VAPID_PUBLIC_KEY'); <--- offending semi-colon
'vapid_private_key' => env('VAPID_PRIVATE_KEY'),
Changed it to the proper comma and everything works as expected.
将其更改为正确的逗号，一切都按预期进行。

I know that this is not the best answer, but it works to me.
我知道这不是最好的答案，但它对我有用。
there is some problem with permission, i do 777 to all laravel project and now it works.
权限有问题，我对所有 Laravel 项目都执行了 777 操作，现在它可以工作了。
some file(s) or directory is the problem, i need a quick fix, but it's not goot to set all 777.
某些文件或目录是问题所在，我需要快速修复，但设置所有 777 并不合适。
