test_zoneinfo failure

Bug report

Bug description:

test_zoneinfo on main has been failing reliably for me for several days now. Environment is MacOS Tahoe 26.1 running on an M1 MacBook Pro, non-framework build. It doesn't fail on the 3.14 or 3.13 branches. See attached error output. I've not tried to dig into the problem, though it seems that perhaps gh-139546 is related?

./python.exe -m test -v test_zoneinfo

zone.txt

CPython versions tested on:

CPython main branch

Operating systems tested on:

macOS

I’ll take a look later, but it doesn’t seem to be related. To confirm, do you have tzdata installed for 3.15? (It’s a package)

To check, can you run import tzdata with the same python you used for the test?

To confirm, do you have tzdata installed for 3.15?

Ah, yes:

>>> import tzdata
>>> tzdata.__version__
'2025.2'

I recall installing a number of packages to allow me to test my Flask app w/ 3.15. tzdata must have come along "for free." After removing ~/.local/lib/python3.15t (which I would typically not have) all tests to pass once again.

Then it indeed is a duplicate, thanks for checking Skip!
