Install modified rasterstats from https://github.com/AsgerPetersen/python-rasterstats/tree/boundless to use this script as is.
Or just modify the bool in this line https://github.com/perrygeo/python-rasterstats/blob/master/src/rasterstats/io.py#L319

Install Anaconda or Miniconda from here https://docs.conda.io/projects/conda/en/latest/user-guide/install/macos.html
Create a conda environment in which you will install QGIS. In this example we call it conda_qgis.
> conda create -n conda_qgis
> conda activate conda_qgis
This is how I debug QGIS using VSCode on OSX. Previously I used this approach. But since then ptvsd was deprecated and I also needed to install python modules backed by native C code. This is much easier to do in a conda based environment (actually, I didn't find a way to make it work with the official QGIS installer :-)).
Follow this description to get QGIS running in conda.
ptvsd is superseded by debugpy.
