When using the latest django from PyPI in CentOS 7, running "./manage.py 
runserver" gives an error about sqlite being too old.
Since there's no newer sqlite version in the CentOS repos, I tried building 
sqlite from scratch:

curl -L https://www.sqlite.org/2019/sqlite-amalgamation-3290000.tar.gz > 
sqlite-amalgamation-3290000.tar.gz
tar -xvf sqlite-amalgamation-3290000.tar.gzcd sqlite-autoconf-3290000
./configure
make
make install


This sets up the latest sqlite3 to /usr/local/bin/.
Since /usr/local/bin is ahead of /usr/bin in my PATH, just running 
"sqlite3" in the terminal runs the latest sqlite.
It runs without issues, and shows that it's the latest version:

my_hostname# sqlite3

SQLite version 3.29.0 2019-07-10 17:32:03 
Enter ".help" for usage hints. 
Connected to a transient in-memory database. 
Use ".open FILENAME" to reopen on a persistent database. 
sqlite>


Running "./manage.py runserver" again, it still tries to use the old 
version in /usr/bin, and fails.
My django is running in a pipenv virtual environment, where PATH still has 
/usr/local/bin/ ahead of /usr/bin, and running "sqlite3" in terminal still 
shows the latest version.

I followed the traceback django gives me to the dbapi2.py module, where to 
figure out the sqlite version it does this:

import _sqlite3
_sqlite3.sqlite_version


If I run "python" in my virtualenv, and type those 2 lines, it shows the 
old version of sqlite too.
_sqlite3 is not written in python - it's a compiled binary, so I can't 
examine it to see where it looks.

Am I missing something?
How can I tell _sqlite3 that there's a newer version of sqlite available on 
the system?
Does _sqlite3 even care about /usr/local/bin/sqlite3? Or is there some 
sqlite library it's looking for?
