bindShared() error when calling php artisan

I have Laravel 5.3 and I have installed the laravel/socialite package v2.0. Now, whenever I call php artisan, I get this error:

[Symfony\Component\Debug\Exception\FatalErrorException] Call to undefined method Illuminate\Foundation\Application::bindShared()

What could be wrong with it? I've googled it and found something about the Illuminate\HTML package, but I don't use it.

Here is my composer.json file:
