This (via the 3.15.0 release) may be responsible for breaking virtualenv. See pypa/virtualenv#2735.

Happening to me too. Stacktrace:

I just encountered this using nox on a project:

TypeError: object.__init__() takes exactly one argument (the instance to initialize)
Exception ignored in: <function BaseFileLock.__del__ at 0x7f49d3407250>
Traceback (most recent call last):

Started whenever 3.15 hit pypi.

@gaborbernat seems like an immediate yank would be good.

happening to me as well, all of our builds in CI stopped building with this error -> the virtualenv package depends on this one so I suspect this is a very widespread failure.

I've been seeing it on python 3.11.9

Also encountering when trying to spin up a venv via poetry:

Exception ignored in: <function BaseFileLock.__del__ at 0x7fc53764b6d0>
