Description

The django-admin.py runserver fails on OS 10.4.4 when the DATABASE_ENGINE is set to 'sqlite3' and pysqlite 2.1.2 is installed (with the standard OS X version of Python 2.3 and sqlite3).

I can import pysqlite2 from the python interactive prompt with no errors, but django-admin.py runserver fails with this traceback:

python manage.py runserver
Validating models...

The runserver works fine with pysqlite 2.0.3, but 2.1.2 is listed as the "latest stable version" for download.

try this:

open a python shell, and execute this :
from pysqlite2 import dbapi2;

does that work?

It seems likely that this is because pysqlite 2.1.2 requires a newer version of sqlite.
See: http://www.initd.org/tracker/pysqlite/ticket/138
either upgrade sqlite or use the 2.0 branch of pysqlite

Resolution: invalid
Status: newclosed

Closing this because it's more likely an version compatibility issue between sqlite and pysqlite.

Might also try pysqlite 2.1.3, which has now been released; according to the release notes, "this branch had issues, seems to be stable now".
