django virtualenv - Error: No module named south

Question

I'm getting this error, when I try this:

source ./env/bin/activate

sudo python manage.py syncdb

Error: No module named south

I installed south after activating virtual env, using pip install south (as well as django).

installed apps in settings.py:

INSTALLED_APPS = (
    'south',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',

What could be the problem?

Update: I get this error when trying to sync without sudo. Maybe it is related with 'south' problem:

(env)andrius@ubuntu:~/djcode/myproject$ python manage.py syncdb

Syncing...

psycopg2.OperationalError: FATAL:  Peer authentication failed for user "django"

I created database and user for database using these commands:

template1=# create database finance;
CREATE DATABASE
template1=# grant all privileges on database finance to django;
ERROR:  role "django" does not exist
template1=# create user django with password 'mydb123';
CREATE ROLE
template1=# grant all privileges on database finance to django;
GRANT
template1=# \q

My database settings in settings.py:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'finance',                      # Or path to database file if using sqlite3.
        'USER': 'django',                      # Not used with sqlite3.
        'PASSWORD': 'mydb123',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }

}

Solution

dont be a sudoer when installing south or running syncdb. just do

pip install south
python manage.py syncdb

Usually I don't use sudo, but I thought it required sudo, because of authentication error. My bad:)

For me, south is not in installed apps but I still get this error. And pip uninstall south reports: south is not installed
