Do you have any idea on what might be causing this error when I execute:
drush si geoslate --db-url='mysql://root:root@localhost/geoslate' --site-name=Geoslate
Command site-install needs a higher bootstrap level to run - you will need to invoke from a more functional Drupal environment to run this command.
The drush command 'si vimn_geoslate' could not be executed.
A Drupal installation directory could not be found
