I had the same issue, the readme doesn't have great instructions for getting started as a brand new user and there's not a lot of help online.
here are my steps:
After installing sphinx i cd to the directory that contains my local git repo for odoorpc
i use sphinx-quickstart
then follow the readme instructions
still no luck so i know im missing something

I did have some success using make html
eg.
odoorpc>make html
output:
