[ludovic coues]

Have you tried "sudo apt-get install sqlite" ?
The package might be called sqlite3 or sqlite-dev or something like that

Totally Lost on "python manage.py runserver"

[Michael Durkin]

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:
