gunicorn.errors.HaltServer: <HaltServer 'Le travailleur n'a pas pu démarrer.' 3>

J'ai installé gunicorn dans mon virtualenv.

De ce répertoire:

manage.py
/onbytes/wsgi.py

Je lance ce qui suit:

gunicorn onbytes.wsgi:application

Et j'obtiens l'erreur suivante:

Traceback (most recent call last):

Il y a probablement un problème dans votre application, pas dans gunicorn.

Essayer:

gunicorn --log-file=- onbytes.wsgi:application

Depuis la version R19, Gunicorn ne se connecte pas par défaut dans la console et l'option --debug est déconseillée.

Ajouter --preload la commande gunincorn m'a montré que je devais faire:

pip install ordereddict

Ce paquet manquait.

J'ai eu un problème similaire et c'est parce que j'exécutais la commande dans le mauvais répertoire. Dans une installation standard Django, essayez d'exécuter gunicorn dans le même répertoire que 'manage.py'

dans mon cas après avoir ajouté --preload à Procfile, je comprends que je devrais installer psycopg2-binary avec pip:

pip install psycopg2-binary
