  Could not find a version that satisfies the requirement python-graphviz (from -r requirements.txt (line 9)) (from versions: )
No matching distribution found for python-graphviz (from -r requirements.txt (line 9))

Looking at the available packages: https://pypi.org/search/?q=graphviz it seems that you want to use this one? https://pypi.org/project/graphviz-python/

Hmm, this indeed seems not to be a pip package. I needed it in my miniconda installation to make it work. I will remove it from the requirements list for now. Have to see what a cross platform for this solution is...

Hi,

This issue shows up when the Visual Studio along with the C++ compiler is not installed correctly

Try following strictly the installation tutorial on the website http://pm4py.pads.rwth-aachen.de/windows/
