Steps to reproduce

The google-api-python-client library requires this library to function. There was a new tag a few hours ago that introduced some changes to the way versioning is being done: d36e896. It doesn't look like the packaging library is being installed as I am getting an error when trying to use the google-api-python-client library.

We are also experiencing the same issue:

ModuleNotFoundError: No module named 'packaging'

As a workaround, you can pin to the previous version of this library until this is fixed:

google-api-core==2.27.0

@jmctune

same issue, used @jmctune's workaround for now

Same issue:

  File "/builds/nuseds/nuseds-tools/calendar_sync/main.py", line 15, in <module>
    from googleapiclient.discovery import build
  File "/usr/local/lib/python3.14/site-packages/googleapiclient/discovery.py", line 42, in <module>
    import google.api_core.client_options
  File "/usr/local/lib/python3.14/site-packages/google/api_core/__init__.py", line 20, in <module>
    from google.api_core import _python_package_support
  File "/usr/local/lib/python3.14/site-packages/google/api_core/_python_package_support.py", line 28, in <module>
    from packaging.version import parse as parse_version
ModuleNotFoundError: No module named 'packaging'

This can also be fixed by installing packaging==25.0

Environment details:

OS type and version: MacOS 15.5
Python version: 3.12.12
pip version: 25.2
google-api-core version: 2.28.0

fix: add missing google auth dependency (#679)

feat: provide and use Python version support check (#832)

Same here. Version 2.28 does not install packaging which means you either have to revert to version 2.27 or install the packaging module.

2.28.1 Fixes this issue 🎉

@parthea

@parthea @daniel-sanche can you please yank 2.28.0 on PyPI now that 2.28.1 was released?

fix: add missing google auth dependency (semaphoreio#679)
