I have a problem enabling CiviCRM 5.24.2 after installation in Drupal 7.69 under PHP 7.2.27 under Centos7 Apache/2.4.6
CiviCRM installs correctly using both UI and CV method - ie builds database & civicrm.settings, but fails to enable (same error in both install methods).
drush en -y civicrm produces the following error (and breaks Drupal site):
WD php: Error: Class 'CRM_Extension_Info' not found in CRM_Extension_Mapper->keyToInfo() Error: Class 'CRM_Extension_Info' not found in CRM_Extension_Mapper->keyToInfo() (line 170 of /srv/web/climatebonds.net/web/sites/all/modules/civicrm/CRM/Extension/Mapper.php). Drush command terminated abnormally due to an unrecoverable error.
drush dis -y civicrm returns site to working order.
No problems with installation under local environment: Apache/2.4.35 (Unix) PHP/7.2.19
