setup.py: error: Could not find module 'geos_c.dll' (or one of its dependencies)...

[BurtHarris]

OK, I gave it a try with a completely different python distribution (anaconda) and a virtual environment (best as I understand it.) Running setup now gives me a different error message. Does this one look familiar to you?

setup.py: error: Could not find module 'geos_c.dll' (or one of its dependencies). Try using the full path with constructor syntax. 

My commands were:

PS C:\try\pcbflow> python -m venv create .venv
PS C:\try\pcbflow> .\.venv\Scripts\activate
(.venv) PS C:\try\pcbflow> python .\setup.py install

it ended with:

Not sure I can help with that one either. Looks like the shapely install issue. See if you can get some insight from here: https://shapely.readthedocs.io/en/stable/

Closing due to no activity and because shapely is now v.2.0.0+
