I am at a loss. My Google-Fu seems to be sub-par as I cannot find an answer to what I'm looking for.

I am running Ubuntu, using Python 3.6.0 (pyenv handles different Python versions for me), have installed SQLite and Apache and ran "pip install django" to get Django on my machine.

I have run through the Django tutorial on installation (https://docs.djangoproject.com/en/1.11/topics/install/#installing-official-release) and made it all the way to "python manage.py runserver". After running that line I get the following message through the shell that I simply do not understand:

~/Scripts/Django_Practice/mysite$ python manage.py runserver

After reading the file listed in the error message (/home/durkin/.pyenv/versions/3.6.0/lib/python3.6/site-packages/django/db/backends/sqlite3/base.py) it makes me think I have a problem with SQLite, but again I'm at a loss. Completely stuck! Does anyone have the answer?
