Laravel - Call to undefined method Illuminate\Foundation\Application::share()

问题

I am upgrading from Laravel 5.3 to Laravel 5.4. Problem is that when I run composer update and when it comes to php artisan optimize part, I get an error:

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

I've read a couple of questions here on StackOverflow and the answer is to replace this share method with singleton. But where can I find this share()?

EDIT

My composer.json file:

Project Share() method file is the Following Path:

Your Project >> Vendor >> laravel >> framework >> src >> Illuminate >> Container >> Container.php

Comment your share() method code and put below code.

public function singleton($abstract, $concrete = null)
{
   $this->bind($abstract, $concrete, true);
}
