gunicorn 19 compatibility

[normaldotcom]

I recently updated to Django 1.7 / gunicorn 19.1.1 and webvirtmgr no longer starts with manage.py. Gunicorn emits an error about the command being depreciated and the server halts.

$ /usr/bin/env python2 /srv/webvirtmgr/manage.py run_gunicorn -c /srv/webvirtmgr/conf/gunicorn.conf.py
WARNING:root:No local_settings file found.
!!!
!!! WARNING: This command is deprecated.

!!!
!!!         See https://docs.djangoproject.com/en/1.5/howto/deployment/wsgi/gunicorn/

Is there an alternative startup method I can use with gunicorn 19?

Hi, I confirm this issue on archlinux

On archlinux I fixed it with:

sed -i -e '/^command=/d' -e '$a command=/usr/bin/gunicorn-python2 webvirtmgr.wsgi:application' /etc/supervisor.d/webvirtmgr.ini
systemctl restart supervisord

as root of course oh and also you need to have gunicorn-python2 installed
