I am trying to install prefect[kubernetes,azure]==1.4.0 using pip.
It get installed successfully with pip<=24.0.
However with any pip>24.0 the installation fails. For example:
# in a venv
pip install pip==24.2 # released on 2024-07-29
pip install prefect[kubernetes,azure]==1.4.0
results in

Use prefect 1.4.1 instead. It's the last version in the 1.x series, and has essentially only bug fixes with respect to version 1.4.0.
One of those bug fixes concerns exactly this non-existent (and malformed) version of the Kubernetes package; see this pull request for prefect.
