Error running 'bash install.sh': option --use-feature: invalid choice: 'in-tree-build'

When running the bash install.sh I'm getting this error:

Usage:
pip install [options] [package-index-options] ...
pip install [options] -r [package-index-options] ...
pip install [options] [-e] ...
pip install [options] [-e] ...
pip install [options] <archive url/path> ...

option --use-feature: invalid choice: 'in-tree-build' (choose from 'fast-deps', 'truststore', 'no-binary-enable-wheel-cache')
install.sh: line 22: 1225 Segmentation fault python setup.py build_ext --inplace

It's related to this line within the install.sh file:

pip install . --use-feature=in-tree-build

The error message is indicating that --use-feature=in-tree-build is not a valid option for the pip install command. The valid choices for --use-feature are fast-deps, truststore, and no-binary-enable-wheel-cache.

The in-tree-build feature was used in pip version 21.3 to allow building packages in their own directory, but I'm using a newer version "pip 24.0".

If I directly run that line, I get the same error:

Looks like a bug/issue in the bash install.sh script to be fixed?
Or is there any workaround/fix for this?

Start by reading install.sh, especially the pip install command and line 22 where python setup.py build_ext --inplace runs. Reproduce the failure with pip 24.0, then verify that the installation completes without the invalid --use-feature error or the reported build failure.
