Drush Version Support
Pantheon currently supports the following Drush versions:
- Drush 11
- Drush 10
- Drush 8
Considerations
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.
See the Drush Drupal Compatibility chart for version compatibility information. Consider the following information when determining which Drush version is best suited for your site:
Drush 10 is available with the addition of the
pantheon.ymlfile, or for site-local installation. It requires Drupal 9 or higher, Composer, and PHP 7.1 or higher.Drush 9 and Drush 10 only work on Drupal 8.4 and higher.
Drush 8 Drush 8 is the only recommended version to use in your
pantheon.ymlfile. It is compatible with Drupal 7.Drush 5 and Drush 7 are available on Pantheon if needed. However, both versions are listed as unsupported by the Drush maintainers, and should be avoided unless absolutely necessary.
We highly recommend running Drush version 8.3.2 or higher when running Drush locally.
