Lumen + Dingo + JWT is not instantiable while building

Question

I am trying to get a basic working foundation for a Lumen + Dingo Rest API, but I am not able to figure out how to peace is all together.

Lumen is working fine, but when I try to add Dingo I get all sorts of errors. From the Dingo documentation I read:

Once you have the package you can configure the provider in your config/api.php file or in a service provider or bootstrap file.

'jwt' => 'Dingo\Api\Auth\Provider\JWT'

or

app('Dingo\Api\Auth\Auth')->extend('jwt', function ($app) {
   return new Dingo\Api\Auth\Provider\JWT($app['Tymon\JWTAuth\JWTAuth']);
});

I have installed a fresh copy of Lumen, and I do not see any config/api.php, so I assume I work with the piece of code to place in my bootstrap/app.php

Well this is what my bootstrap/app.php looks like:

<?php

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

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

$app->register(Dingo\Api\Provider\LumenServiceProvider::class);

app('Dingo\Api\Auth\Auth')->extend('jwt', function ($app) {
    return new Dingo\Api\Auth\Provider\JWT($app['Tymon\JWTAuth\JWTAuth']);
});

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

return $app;

When running this I get the following error:

BindingResolutionException in Container.php line 752:

Target [Tymon\JWTAuth\Providers\JWT\JWTInterface] is not instantiable while building [Tymon\JWTAuth\JWTAuth, Tymon\JWTAuth\JWTManager].

at Auth->extend('jwt', object(Closure)) in app.php line 96
at require('/vagrant/dev_src/api/bootstrap/app.php') in index.php line 14

Only when I remove the following piece of code it works again:

app('Dingo\Api\Auth\Auth')->extend('jwt', function ($app) {
    return new Dingo\Api\Auth\Provider\JWT($app['Tymon\JWTAuth\JWTAuth']);
});

.env file:

There's a lot you must to do. Here's the guide:

You have to manually bind the CacheManager implementation:

$app->singleton(
    Illuminate\Cache\CacheManager::class,
    function ($app) {
        return $app->make('cache');
    }
);

You also need to bind AuthManager implementation:

$app->singleton(
    Illuminate\Auth\AuthManager::class,
    function ($app) {
        return $app->make('auth');
    }
);

Before you register Dingo\Api\Provider\LumenServiceProvider, you have to register Tymon\JWTAuth\Providers\JWTAuthServiceProvider.

$app->register(Tymon\JWTAuth\Providers\JWTAuthServiceProvider::class);
$app->register(Dingo\Api\Provider\LumenServiceProvider::class);

Before you register Tymon\JWTAuth\Providers\JWTAuthServiceProvider you need to make a config_path function, since Lumen doesn't support this global function.

/**
 * Because Lumen has no config_path function, we need to add this function
 * to make JWT Auth works.
 */
if (!function_exists('config_path')) {
    /**
     * Get the configuration path.
     *
     * @param string $path
     *
     * @return string
     */
    function config_path($path = '')
    {
        return app()->basePath().'/config'.($path ? '/'.$path : $path);
    }
}

Here's my full bootstrap/app.php file:

<?php

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->singleton(
    Illuminate\Contracts\Routing\ResponseFactory::class,
    Illuminate\Routing\ResponseFactory::class
);

$app->singleton(
    Illuminate\Auth\AuthManager::class,
    function ($app) {
        return $app->make('auth');
    }
);

$app->singleton(
    Illuminate\Cache\CacheManager::class,
    function ($app) {
        return $app->make('cache');
    }
);

/*

|
*/

// $app->middleware([
//    App\Http\Middleware\ExampleMiddleware::class
// ]);

// $app->routeMiddleware([
//     //
// ]);

/*
|--------------------------------------------------------------------------

*/

// $app->register(App\Providers\AppServiceProvider::class);
// $app->register(App\Providers\AuthServiceProvider::class);
// $app->register(App\Providers\EventServiceProvider::class);

// JWTAuth Dependencies
/**

if (!function_exists('config_path')) {
    /**
     * Get the configuration path.
     *
     * @param string $path
     *
     * @return string
     */
    function config_path($path = '')
    {
        return app()->basePath().'/config'.($path ? '/'.$path : $path);
    }
}

$app->register(Tymon\JWTAuth\Providers\JWTAuthServiceProvider::class);
$app->register(Dingo\Api\Provider\LumenServiceProvider::class);

$app->make(Dingo\Api\Auth\Auth::class)->extend('jwt', function ($app) {
    return new Dingo\Api\Auth\Provider\JWT(

I make a simple POC using Lumen with Dingo API here.
