pip failing - ERROR: No matching distribution found for sip==4.19.8

Running on Arch, I got an error trying to install via the pip command in the README.md.

I believe this log should provide all the details:

I'm not really familiar with pip so maybe I'm missing something obvious here?

Very good point - it isn't mentioned in the readme, but fbs only supports versions up to Python 3.6, so you'll need to create your virtualenv using Python 3.6. I'll update the readme. You'll also now run in to issues because the pulseaudio plugin is built from source rather than included in the VCS. I should have this fixed within a day.

I've updated README.md with clearer instructions as to how to get Cadmus up & running from source, please re-open this if you have further questions.
