Laravel Upgrade Error With Whoops

I just updated my Laravel 5.4.23 to 5.5 and tried running my tests for PHPUnit and I am receiving the following error and I am trying to scour around the internet and find out people who have done so and have received the same error message but have not had any luck.

Has anyone received this error?

Call to undefined method Whoops\Handle\PrettyPageHandler::setApplicationPaths()
