programs not compiling

lately I have been trying to compile some programs from slackbuilds.org, I'm running slackware current and I get this error. 'ModuleNotFoundError: No module named 'giscanner._giscanner'. I think it's a python module and i have no idea what it is and how to install it with pip install and it returns the following. pkg_resources.DistributionNotFound: The 'pip==20.2' distribution was not found and is required by the application. I don't know what to do at this point. python version is 3.7.2 and 2.7.18 if that is helpful.
