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?
