Installation Error on macOS: UserWarning: Core Pydantic V1 isn't compatible with Python 3.14 or greater

I'm trying to install CumulusCI on macOS according to the Install CumulusCI trailhead module, which points to the CumulusCI docs. 

After doing "brew install pipx", "pipx ensurepath", and "pipx install cumulusci", I try to verify the installation with "cci version" and get the following errror:

/Users/nathanoday/.local/pipx/venvs/cumulusci/lib/python3.14/site-packages/pydantic/__init__.py:137: UserWarning: Core Pydantic V1 functionality isn't compatible with Python 3.14 or greater.

I've tried uninstalling and reinstalling via pipx but no luck. My Python version is 3.14.2 . Does anyone have any ideas?
