Error setting up South in a new Django project

I'm working on a new django project and following this tutorial. I'm at the step "Using South for Database Migrations", attempting to run python manage.py syncdb, and I'm getting the following error:

(editorial)[hookedonwinter@hookedonwinter editorial (master *)]$ python manage.py syncdb
Traceback (most recent call last):

TypeError: Error when calling the metaclass bases
    __init__() keywords must be strings

Here is my settings.py file: https://gist.github.com/pjhoberman/5273653

There are no apps yet, just an empty project. I'm guessing it's a simple overlook on my part - any thoughts?

Edit

From the comments:

Edit2

I started over and used django 1.4, and it works.

Edit3

I updated python to 2.7 and used django 1.5, and it all works as well.

You need Python 2.6.5+ to run Django 1.5. That's why downgrading to Django 1.4 or upgrading to Python 2.7 was what solved your problem.

The "TypeError" at the bottom is the solution. You get this error from Django 1.5 if you use a Python version lower than 2.6.5. There is a Django bug report and a SO discussion on the issue. Arguably the error message is less than intuitive.

The OP is right, none of the answers solved this problem. The solutions are: 1) upgrade Python to 2.7, 2) downgrade Django to 1.4.

None of the answers actually solved the problem, so I'm answering it myself since I can't delete the question now that there's bounty.

I think the problem is with that "~" character you have on your database setting. Try putting #coding=utf-8 as the first or second line of your settings and see what happen.

If that doesn't resolve your problem, change the database filename for one on the same directory of manage.py file like this:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'databasename.sql',
    }
}

I tried making a new environment following that tutorial you post and i have no problem. But when i tried to use a database name as you were trying (the one with "~" in its name) i get this error:

(env) user@pc:/path >$  python manage.py syncdb --noinput
Syncing...
OperationalError: unable to open database file

I bet that symbol is the root of your problem... Tell us if this solved your problem!

It seems a DB config problem, try this. On the top of the file:

import os

then:

PROJECT_DIR = os.path.abspath(os.path.dirname(__file__))
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(PROJECT_DIR, 'yourdatabasename.db'),
    }
}

And finally a syncdb should do the trick. Also you can try "python manage.py reset south" to fix possible problems in the APP. If this doesn't work i suggest you start a new problem to discard other errors.

South is very well documented and i'm sure you'll be clear after going through it.

This is the tutorial.

http://south.readthedocs.org/en/0.7.6/tutorial/part1.html

Still to make life simpler..

1) Download south and add it to your apps directory.
2) Add 'south' to INSTALLED APPS in settings.py
3) Run syncdb
4) $ ./manage.py schemamigration appname --initial
5) $ ./manage.py migrate appname

This is all you need for a very basic start.
