Ошибка Python с devstack

Question

Может ли кто-нибудь помочь мне с этой ошибкой:

No handlers could be found for logger "openstack_dashboard.settings"
    Traceback (most recent call last):

я запускаю devstack (минимальная версия openstack), и когда я запускаю./stack.sh, я получаю ошибку с python2.7 (django)

Спасибо
