参数2传递给Arubacao \ BasicAuth \ BasicGuard :: __ construct（）必须是Illuminate \ Contracts \ Auth \ UserProvider的实例，给出null

Question

一直试图使用lumen作为简单轻巧的REST API界面，使用流明+ arubacao/http-basic-auth-guard作曲家包。

我遇到了一个瓶颈问题：

Argument 2 passed to Arubacao\BasicAuth\BasicGuard::__construct() must be an instance of Illuminate\Contracts\Auth\UserProvider, null given,
called in /Applications/MAMP/htdocs/app.mydomain.com/api/vendor/arubacao/http-basic-auth-guard/src/BasicGuardServiceProvider.php on line 38

config / auth.php的内容：

return [

    'defaults' => [
        'guard' => env('AUTH_GUARD', 'api'),
    ],

    'guards' => [
        'api' => [
            'driver' => 'basic',
            'provider' => 'users'
        ],

        // ...
    ],

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model'  => App\User::class
        ],
    ],

    'providers' => [
        //
    ],

    'passwords' => [
        //
    ],

];

bootstrap / app.php的内容

require_once __DIR__.'/../vendor/autoload.php';

try {
    (new Dotenv\Dotenv(__DIR__.'/../'))->load();
} catch (Dotenv\Exception\InvalidPathException $e) {
    //
}

$app = new Laravel\Lumen\Application(
    realpath(__DIR__.'/../')
);

$app->withFacades();

$app->withEloquent();

$app->singleton(
    Illuminate\Contracts\Debug\ExceptionHandler::class,
    App\Exceptions\Handler::class
);

$app->singleton(
    Illuminate\Contracts\Console\Kernel::class,
    App\Console\Kernel::class
);

$app->routeMiddleware([
    'auth' => App\Http\Middleware\Authenticate::class,
]);

$app->register(App\Providers\AuthServiceProvider::class);
$app->register(Arubacao\BasicAuth\BasicGuardServiceProvider::class);

$app->router->group([
    'namespace' => 'App\Http\Controllers',
], function ($router) {
    require __DIR__.'/../routes/web.php';
});

return $app;

*设置与记录的in arubacao/http-basic-auth-guard repo相同

return [

    'defaults' => [
        'guard' => env('AUTH_GUARD', 'api'),
    ],

    'guards' => [
        'api' => [
            'driver' => 'basic',
            'provider' => 'users'
        ],

        // ...
    ],

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model'  => App\User::class
        ],
    ],

// This should be removed, it was leftover from the boiler template of lumen repo.
    'providers' => [
        //
    ],
