Target [Illuminate\Contracts\Routing\ResponseFactory] is not instantiable - lumen

Question

I am trying to return a response like this:
return response()->json(['name' => 'Abigail', 'state' => 'CA']);
however, I got error:
Target [Illuminate\Contracts\Routing\ResponseFactory] is not instantiable.
Any idea?
Here is my composer.json:

I still get the error in 2020. Here's an updated version of the solution by #sunben:
In bootstrap/app.php, uncomment the following line
$app->register(App\Providers\AppServiceProvider::class);
Then in app\Providers\AppServiceProvider.php, update register method to add:
$this->app->singleton(\Illuminate\Contracts\Routing\ResponseFactory::class, function() {
return new \Laravel\Lumen\Http\ResponseFactory();
});

Might be late but found the solution.
In bootstrap/app.php, uncomment the following line
$app->register(App\Providers\AppServiceProvider::class);
Then in app\Providers\AppServiceProvider.php, update register method to add:
public function register()
{
$this->app->singleton('Illuminate\Contracts\Routing\ResponseFactory', function ($app) {
return new \Illuminate\Routing\ResponseFactory(
$app['Illuminate\Contracts\View\Factory'],
$app['Illuminate\Routing\Redirector']
);
});
}

Answer 3

The response helper may be used to conveniently generate other types of response instances. When the response helper is called without arguments, an implementation of the Laravel\Lumen\Http\ResponseFactory class is returned.
use Laravel\Lumen\Http\ResponseFactory;

Answer 4

Try like this
public function register() { $this->app->singleton(\Illuminate\Contracts\Routing\ResponseFactory::class, function() { return new \Laravel\Lumen\Http\ResponseFactory(); }); $this->app->bind(\Illuminate\Contracts\Routing\UrlGenerator::class, function ($app) { return new \Laravel\Lumen\Routing\UrlGenerator($app); }); }

Answer 5

call
use Tests\TestCase;
instead of
use PHPUnit\Framework\TestCase;
your function depends on another function, So you should extend like feature test and not unit tests.

Answer 6

Those who are still getting routing related error, just put the following line in your composer.json file and run the command composer update
"illuminate/routing": "^5.6"
composer update
and boom here we go, wish all things are working great now

#sunben's answer worked for me but I added the following inside the register method
$this->app->bind(\Illuminate\Routing\RouteCollectionInterface::class, function ($app) { return new \Illuminate\Routing\RouteCollection; });
