It is a pure django project created by pycharm. I was following the document of django_facebook, installation section. What I do is just get facebook app and type the code 'django_facebook' in INSTALLED_APP in settings.py.
It's same results when syncdb also.
I'm using python-2.7.5 and django-1.6.5.
I can't find any answer to solve this. anybody knows this?

Regarding the warningNo handlers could be found for logger "django_facebook.models" and not the error. This question came up on search for that warning, thought this would be useful for others.
django-facebook outputs logs when in operation, just like other django components do. You have to tell Django what you want to do with these messages. In django terminology the app outputs some messages as a logger without needing to know what to do with them, you have to then patch these to a handler which doesn't know anything about your use case, but does know about sending emails/texts/carrier pigeons.
In your settings.py file find LOGGING=..., in the loggers dict you will have to specify what handlers you want to handle the output from django-facebook.
For more information see the docs on logging https://djangoproject.com/en/dev/topics/logging/
My logging variable looks like this, notice the bit at the bottom:
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'filters': {
'require_debug_false': {
'()': 'django.utils.log.RequireDebugFalse'
}
},
'handlers': {
'mail_admins': {
'level': 'ERROR',
'filters': ['require_debug_false'],
'class': 'django.utils.log.AdminEmailHandler'
},
'console': {
'level': 'DEBUG',
'class': 'logging.StreamHandler',
},
},
'loggers': {
'django.request': {
'handlers': ['mail_admins','console'],
'level': 'ERROR',
'propagate': True,
},
'django_facebook.models': {
'handlers': ['mail_admins','console'],
'level': 'ERROR',
'propagate': True,
}
}
}

You could try pip install pillow
