[postgis-users] Installation Error

[Smaran Harihar]

Hi,

I tried installing GeoDjango on Ubuntu and assumed that GEOS and Proj
existed on Linux and directly installed PostGIS.

Now I ran the tests as given on the Django
site<https://code.djangoproject.com/wiki/GeoDjangoInstall#Third-PartyLibraryInstallationTests>,
and this is the output I am receiving

>>>from django.contrib.gis.tests import test_gdal
Traceback (most recent call last):

line 40, in _setup
    raise ImportError("Settings cannot be imported, because environment
variable %s is undefined." % ENVIRONMENT_VARIABLE)
ImportError: Settings cannot be imported, because environment variable
DJANGO_SETTINGS_MODULE is undefined.

Should I uninstall PostGIS and install GEOS and PROJ or should I install
them over PostGIS? Also how do I uninstall PostGIS?
