AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?

I am getting an error trying to both install from source and install via pip install PyWavelets.

This is on python version 3.12, with a fully updated pip version. The error is the same whether I use "pip install PyWavelets" or do "pip install ." when inside the source directory.

I get the following error:

Can confirm. Had the same errors when attempting to install on Fedora 39 (which uses Python-3.12)

Also having this issue on Python 3.12 inside Ubuntu on WSL2.

The 1.5.0 release with the fix is up on PyPI now, so closing. Thanks all.
