export export LD_LIBRARY_PATH=$HOME//sqlite3/lib

I’ve added it next to the line export PATH in the activate file:

PATH="$VIRTUAL_ENV/bin:$PATH"
export PATH
export LD_LIBRARY_PATH=$HOME/…/sqlite3/lib  # <- Here

One can check it in either one of two ways.

From Python in the virtualenv, first do:

>>> import _sqlite3
>>> _sqlite3.__file__
'/usr/lib/…/_sqlite3.cpython-35m-i386-linux-gnu.so'

Then exit Python and run ldd on the string returned:

$ ldd /usr/lib/…/_sqlite3.cpython-35m-i386-linux-gnu.so
> …
> libsqlite3.so.0 => /home/…/sqlite3/lib/libsqlite3.so.0
> …

Or alternatively, again in Python from the virtualenv:

>>> import sqlite3
>>> sqlite3.sqlite_version
'3.21.0'  # Was 3.11.8 before
