Brandon Williams commented on CASSANDRA-18472:
----------------------------------------------

[~djoshi] I agree we don't want to be in this situation again, but it's 
probably a nuanced enough topic worth raising on dev.

After removing python2, I encountered the same issue I opened this ticket with, 
except for python3.6! This revealed the real culprit, virtualenv. It appears to 
be specific to virtualenv from pip on 3.11, so I installed the Ubuntu package 
instead which should be more stable and allowed removal of my previous 
2.7-specific hack.  This just left paring the 2.7 requirements down to only 
cassandra-driver, which I did 
[here|https://github.com/driftx/cassandra-builds/tree/CASSANDRA-18472] and 
built and pushed the image to my docker.
