You can just download the library manually and stick it in your Phython's lib folder. I've done it in the past with things that weren't in the repos. I forget which folder exactly so if you're not sure if you have it in the right place, just open a Python terminal and try to import it. If it's not the right place it'll fail. I'm on mobile right now, so if somebody doesn't beat me to it, this evening I'll try to get on my PC and see what directory works and then edit this answer.
