Drush Version Support

Pantheon currently supports the following Drush versions:

  • Drush 11
  • Drush 10
  • Drush 8


Drush only supports one install method. Your Drupal site is required to be built with Composer and your Drush must be compatible and listed as a dependency. Consider the following information when determining which Drush version is best suited for your site:


We highly recommend running Drush version 8.3.2 or higher when running Drush locally.
