Facing issue with pretty table and python 2.7.

[sachintaware]

This seems to be an old repo and not sure if amazon glacier cmd is supported. The documentation seems to have only aws cli method to communicate with glacier. This by default takes python 2.7 and gives error with pretty table. Tried installing pretty table and still does not work. Can we force using python 3.8 ? As that is the version seems to work with pretty table or can the below error be resolved?

Traceback (most recent call last):

pkg_resources.DistributionNotFound: The 'prettytable' distribution was not found and is required by glacier

It doesn't seem to work with python 3 because it uses python 2 print statements. I'm not sure if that's the only incompatibility.

I'm also having issues with python 2.7. Not the same error, but also related with prettytable:
