3.1 too many "No matching distribution found for xyz" errors

[rapidcrawler]

Current requirements.txt is throwing too many No matching distribution found for xyz errors. I've personally tried to manually update my local requirements file, e.g. Fiona, cffi, etc versions. But the errors just keeps popping for every other library and run, as the last update to this repo and requirement file was 3-4 years old.
It's getting too difficult to even start with the initial chapters of the book. Can you please update the requirements.txt file? It would be very helpful for us. Thank you.
