kubernetes-validate 1.28.1 fails to import

[faust64]

Hi,

I am using Ansible kubernetes module, with some "validate" option that relies on kubernetes-validate
https://docs.ansible.com/ansible/latest/collections/kubernetes/core/k8s_module.html#parameter-validate

As of upgrading kubernetes-validate from 1.27.1 to 1.28.1, I noticed my playbooks would fail with an error such as

failed to import the required Python library (kubernetes-validate) on [my_hostname]'s Python /usr/bin/python3. Please read the module documentation and installl it in the appropriate location ... if the module is installed ... consult the documentation on ansible_python_interpreter)

I did attempt to rebuild that image, same issue showing.

Using ansible core, 2.15.0.
Python 3.9.18 and Python 3.11.15 are present in image.
When I do some ansible --version, python 3.9 is the one in use ... while in doubt, all "pip install" we have building this image would run for both python versions, ... I can confirm pip3.9 list and pip3.11 list would both show kubernetes-validate to be installed.

Downgrading to 1.28.0, my playbooks are happy with this.
I'm not yet sure what could be wrong here ... In doubt asking here, does this ring a bell?!

Hi @faust64 ok, I've reproduced this - I missed a dependency in the most recent merged PR.

The quick fix is to install the typing_extensions module.

I'll release a fixed 1.28.2 shortly that adds the dependency on that module (and also see if I can work out how to add a test for that kind of problem)

oh, great! thanks a lot!

#28 fixed this problem (including a change to the test suite so that this is less likely to happen in future) and I've just pushed 1.28.2 to pypi

looks great, thanks again!
