title: Laravel Failing on php artisan migrate after php artisan make:auth
body: <p>I decided to test the new Laravel. So I started with the basic commands:</p>
  
  <pre><code>$ laravel new blog
  
  $ php artisan make:auth
  
  $ php artisan migrate
  </code></pre>
  
  <p>and I edited my AppServiceProvider.php file and add to the boot method a default string length</p>
  
  <pre><code>use Illuminate\Support\Facades\Schema;
  
  function boot()
  {
      Schema::defaultStringLength(191);
  }
  </code></pre>
  
  <p>But I still have an error:</p>
  
  <pre><code>  [Symfony\Component\Debug\Exception\FatalErrorException]
    Call to undefined method Illuminate\Database\Schema\MySqlBuilder::defaultStringLength()
  </code></pre>
