Problemas con la instalación de psycopg2/Python path

Question

Creé un virtualenv en mi carpeta de aplicaciones django, y allí instalé todas mis dependencias de python. Mi proyecto Django se llama tema, por lo que en la carpeta del tema hay una carpeta de venv que contiene las libs de python. Si ejecuto python manage.py syncdb arroja Error was: No module named postgresql_psycopg2.base. Aquí está el rastreo:

(venv)app@domain-VirtualBox:~/dj/theme$ python manage.py syncdb 
Traceback (most recent call last): 
    File "manage.py", line 14, in <module> 
    execute_manager(settings)

    File "/home/app/dj/theme/venv/local/lib/python2.7/site-packages/django/db/utils.py", line 51, in load_backend 
    raise ImproperlyConfigured(error_msg) 
django.core.exceptions.ImproperlyConfigured: 'postgresql_psycopg2' isn't an available database backend. 
Try using django.db.backends.postgresql_psycopg2 instead. 
Error was: No module named postgresql_psycopg2.base 

Pero la cosa es que si intento importar psycopg2 desde una línea de comandos Python, funciona:

(venv)app@domain-VirtualBox:~/dj/theme$ python 
Python 2.7.3 (default, Apr 20 2012, 22:44:07) 
[GCC 4.6.3] on linux2 
Type "help", "copyright", "credits" or "license" for more information. 
>>> import psycopg2 
>>> quit() 

y aquí está mi camino pitón:

>>> import sys 
>>> print sys.path 
['', '/home/app/dj/theme/venv/local/lib/python2.7/site-packages/distribute-0.6.24-py2.7.egg', '/home/app/dj/theme/venv/local/lib/python2.7/site-packages/pip-1.1-py2.7.egg', '/home/app/dj/theme/venv/lib/python2.7/site-packages/distribute-0.6.24-py2.7.egg', '/home/app/dj/theme/venv/lib/python2.7/site-packages/pip-1.1-py2.7.egg', '/home/app/dj/theme/venv/lib/python2.7', '/home/leonsas/dj/theme/venv/lib/python2.7/plat-linux2', '/home/app/dj/theme/venv/lib/python2.7/lib-tk', '/home/app/dj/theme/venv/lib/python2.7/lib-old', '/home/app/dj/theme/venv/lib/python2.7/lib-dynload', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/home/app/dj/theme/venv/local/lib/python2.7/site-packages', '/home/app/dj/theme/venv/lib/python2.7/site-packages'] 
>>> quit() 

Y el whereis python:

(venv)app@domain-VirtualBox:~/dj/theme$ whereis python 
python: /usr/bin/python2.7 /usr/bin/python /usr/bin/python2.7-config /etc/python2.7 /etc/python /usr/lib/python2.7 /usr/bin/X11/python2.7 /usr/bin/X11/python /usr/bin/X11/python2.7-config /usr/local/lib/python2.7 /usr/include/python2.7 /usr/share/python /usr/share/man/man1/python.1.gz 

Creo que el problema está ahí, pero no estoy seguro de cómo solucionarlo. ¿Algunas ideas?

Answer 1

tratar de seguir la sugerencia de la django.core.exceptions.ImproperlyConfigured excepción: uso 'django.db.backends.postgresql_psycopg2' en lugar de 'postgresql_psycopg2' en DATABASES en la configuración de
