v5.1 breaks hatch
Hi,
it seems the latest release 5.1 introduced unconditional print statements which may not be the best idea Claude ever had and also has hatch trip when trying to create venvs.
To reproduce this I created a fresh hatch project, added pip-system-certs as dependency and ran:
hatch env createThat results in this error:
