I'm trying to learn how to build smart contracts in python, but when I try to install contracting from a terminal, I receive this error:

I'm trying to use Mongo DB. I have a few versions of Python installed, including 3.6.0, but I haven't really used Python before and don't really know what I'm doing. I've received a few different messages while trying to fix this, but this is what it's showing now.
