Why does laravel say that the controller is not found?

Question

Laravel

I created the 'Main' controller, the controller has the 'index' function, I wrote in it:

public function index()
    {
        return view('index');
    }

I wrote in Routes:
Route::get('/', '[email protected]');
And laravel itself gives such an error

Answer 1

Your Main appears to be inheriting from \App\Http\Controllers\Controller which doesn't exist
