uwsgi не запускается в Ubuntu Ubuntu 18.04.1 LTS

Я слежу за этим руководством по установке Askbot, и он идет хорошо до самого конца, когда я не могу запустить uWsgi with:

sudo systemctl restart uwsgi

Я получаю следующие ошибки:

sudo systemctl restart uwsgi
Job for uwsgi.service failed because the control process exited with error code.
See "systemctl status uwsgi.service" and "journalctl -xe" for details.
