title: Deprecated: Method ReflectionParameter::getClass() is deprecated in Laravel Illuminate Container.php
body: <p>I recently tried creating a new Laravel project using the <code>laravel new</code> command and going to the {projectname}.test domain returns the error Deprecated: Method ReflectionParameter::getClass() is deprecated in /Users/.../blog/vendor/laravel/framework/src/Illuminate/Container/Container.php
  I have my computer's version of php 7.4 required in my composer.json file and I am using Laravel Installer 4.2.4. My projects created in a CMS built with Laravel all show up fine when typing their .test domains so I'm not sure what is wrong with this installation/the Illuminate container. Any advice greatly appreciated, thanks!</p>
