New install is failing immediately with "ModuleNotFoundError: No module named 'imp'"

[Pito Salas]

I must have something messed up. I am not using env. I simply installed with pip. No "extras".  Here's the trace:

Hi,

the plugin system Nikola is using (yapsy) is not compatible with
Python 3.12. You can try installing Yapsy from GitHub, it might yield
better results: https://github.com/tibonihoo/yapsy/issues/16

Thanks. What;'s the latest python that would work?

[Pito Salas]

Actually... I found yapsy 2.0.0 on GitHub per your pointer. Thanks. But Nikola still not happy (see below.)

As I am choosing a static site generator for my blog, I think these issues disqualify Nikola for me. Can you suggest a reasonable substitute?

Thanks!

We cannot suggest substitutes.
We welcome contributions to make it work with Python 3.12. Python,
unfortunately, removes things it considers "old" at random, and Yapsy
hasn’t seen new releases in a while.

Thanks for your rapid response!
