title: Laravel 9 require laravel/ui to use Auth::routes
body: <p>I am upgrading my project to Laravel 9. However, when I tried to run <code>php artisan</code>, I got an error message.</p>
  <blockquote>
  <p>In Auth.php line 60: To use the Auth::routes() method, please install
  the laravel/ui package.</p>
  </blockquote>
  <p>So I install the package, but I still get the same error message.
  What might be the problem, and how can I fix it?</p>
