No such file or directory in Drupal\Component\DependencyInjection\PhpArrayContainer->createService() I installed a fresh D8 (Drupal 8.6.15) site on my local dev and I am unable to use drush. 

After I installed the site, I also did a composer install. My dev is set up on php 7.1 using AMMPS and drush 8.1.18.

I needed to use drush 9.6 and updated that by composer require drush/drush:"^9.6". Thanks drugan!
