Whoosh utilisation / erreur avec django-haystack - django, django-haystack, whoosh

J'ai une application Django dans laquelle j'essaie d'utiliser django-haystack, donc suivi comme ci-dessous

Django-haystack installé

pip install django-haystack

installée Whoosh

pip install Whoosh(https://bitbucket.org/mchaput/whoosh/wiki/Home)
also tried
downloading from https://pypi.python.org/pypi/Whoosh/#downloads

Alors quand j'ai essayé pip freeze je peux voir la version de sortie comme Whoosh==2.5.6

Paramètres de la botte de foin Django

HAYSTACK_SITECONF = "proj-web.search_sites"
HAYSTACK_SEARCH_ENGINE = "whoosh"
HAYSTACK_WHOOSH_PATH = (os.path.join(os.path.dirname(__file__), "search_index/"))

Et quand j'ai essayé d'exécuter le serveur, je vois le message d'erreur ci-dessous dans le navigateur

Exception Type: MissingDependency at /
Exception Value: The "whoosh" backend requires the installation of "Whoosh". Please refer to the documentation.

Alors, comment résoudre l'erreur ci-dessus? pourquoi il demande Whoosh même si c'est déjà installé?

Je vois que tu as un haystack module dans votre projet (/home/user/user/apps/proj-web/proj_name/haystack/). Supprimez ce dossier, activez votre virtualenv et exécutez:

pip uninstall django-haystack && pip install django-haystack

pour être sûr que tout va bien.

Essayez ensuite de configurer votre botte de foin comme ceci:

import os
HAYSTACK_CONNECTIONS = {
"default": {
"ENGINE": "haystack.backends.whoosh_backend.WhooshEngine",
"PATH": os.path.join(os.path.dirname(__file__), "search_index"),
},
}
