Problems with python3.12

[tibeer]

Hi! I recently upgraded to python3.12 and tried to install markdown-pdf the usual way with pip (I'm on MacOS by the way).

Unfortunately the installation is stuck for quite some time on this step:

user@device ~ % pip3 install markdown-pdf
Collecting markdown-pdf
  Using cached markdown_pdf-1.1-py3-none-any.whl.metadata (3.3 kB)
Collecting PyMuPDF==1.23.3 (from markdown-pdf)
  Using cached PyMuPDF-1.23.3.tar.gz (60.5 MB)
  Installing build dependencies ... done
  Getting requirements to build wheel ... done
  Preparing metadata (pyproject.toml) ... \

after 5min or so the installation fails with a huge error log that exceeds my console. The last few files look like this:

The problem does not occur when using other pip packages. I'm happy to provide more logs if needed :)

Seems like problem with PyMuPDF with Python 3.12 at MacOS.

I updated the PyMuPDF link from 1.23.3 to 1.24.2 (latest) and roll out new release 1.2 of markdown-pdf.

I can't verify the installation under MacOS. Try it for yourself with version of markdown-pdf 1.2. If the installation error does not disappear, then ask the PyMuPDF developers.

Awesome! That solved the problem. Thank you so much!
