I need to install psycopg2 v2.4.1 specifically. I accidentally did:
pip install psycopg2
pip install psycopg2==2.4.1
That installs 2.4.4 instead of the earlier version.
Now even after I pip uninstall psycopg2 and attempt to reinstall with the correct version, it appears that pip is re-using the cache it downloaded the first time.
How can I force pip to clear out its download cache and use the specific version I’m including in the command?
If using pip 6.0 or newer, try adding the
--no-cache-dir option (source).
If using pip older than pip 6.0, upgrade it with
pip install -U pip.
