DateTime of version 3.0+ cannot be pickled without timezone · Issue #899 · python-pendulum/pendulum · GitHub

I am on the latest Pendulum version.
[x ] I have searched the issues of this repo and believe that this is not a duplicate.
OS version and name: MacOS Sonoma 14.6.1, FreeBSD 13.2
Python: 3.11
Pendulum version: 2.1.2, 3.0, 3.1.0

Issue

Pickling a pendulum DateTime does not work anymore.

import pickle, pendulum
dt = pendulum.now()
with open("datetime.pkl", "wb") as f:
    pickle.dump(dt, f)

This works fine with pendulum 2.1.2, but in 3.0 or 3.1.0 I get:

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
_pickle.PicklingError: Cannot pickle a ZoneInfo file from a file stream.
