However the following packages replace it:
python3-pip

E: Package 'python-rpi.gpio' has no installation candidate
E: Package 'python-pip' has no installation candidate
E: Package 'python-pil' has no installation candidate
E: Package 'python-numpy' has no installation candidate

• List the steps to reproduce the problem below (if possible attach code or commands
  to run):
  sudo apt install python-rpi.gpio python-spidev python-pip python-pil python-numpy

what worked for me was:
sudo apt install python3-rpi.gpio python3-spidev python3-pip python3-pil python3-numpy

I dont know if this is just with newer releases of raspbian, but maybe this should be mentioned in the installation guide

Having the same issue, but it does not pertain to this library or this repository. It appears that almost all python packages in the new Raspberry Pi OS package manager are broken. This is probably because RPiOS is trying to move more toward Python3 instead of Python2.

Looks like I updated the instructions as of 5c16bae but these changes haven't yet made it to a release.
