I am new to both python and django. I am trying to get python 3.4 and django 1.6.4 working within a pyvenv-3.4 environment on Linux Mint Mate 13. I followed the procedures of Using a virtual environment with Python 3.4 for "Building Python 3.4 from source" and "Using pyvenv-3.4". Then following the Django tutorial at Writing your first Django app, I was able to create "mysite" with startproject. But the command "python manage.py runserver" failed with django.core.exceptions. ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): No module named '_sqlite3'
Sorry, I do not recall why I resorted to compiling from source, but it may be that I was unable to find pyvenv in the standard Ubuntu downloads using apt-get. In any case, the Makefile for the source distribution does not have an "uninstall" target, so it seems I am stuck with whatever make installed, and without a plan for what to do next to actually get pyvenv-python-django working.
I am updating this post by attaching the full error:
$ python manage.py runserver
