Некоторая команда пастера не работает в ckan 2.7.3

Попытка использовать информацию в:

http://docs.ckan.org/en/ckan-1.4.3/authorization.html

создавать пользователей и назначать роли для конкретного пакета, а команда право не работает.

Например:

paster --plugin=ckan rights -c /etc/ckan/default/development.ini list

Я получаю сообщение об ошибке:

но если я создам пользователя следующим образом:

работает нормально, поэтому я не думаю, что проблема была в моей среде.

Примечание.
