No module named pkg_resources when installing

[dario-99]

When downloading module at version 0.4.6 with python 3.10.12. it gives me No module named pkg_resources when it builds the module.

Machine: all our amazon-linux ec2 machine.

Tried:

1. installing setup_tools
2. downloading build-essential for c/c++ compiler

This error happens when i install the module in the system interpreter and also when i'm building a container with this module as a dependency.
The build with the same machine and dependency was working 10 days ago.

setuptools 72 removed pkg_resources. Its use needs to be replaced. The following removes use of pkg_resources:

More involved patch also removes use of build_ext could as it is not needed just to set the include directory:

Thanks for bringing up this issue. We have addressed it, and released the fix on PyPI. Running pip install py-stringmatching should resolve this issue. Feel free to follow up if you are still having issues.

It seems that the only platform supported is MACOS

I have uploaded the built distributions for Linux and Windows, and they should be available now. Please let us know if you face other issues!
