keep-it-markdown: Python errors and login problem

I am having a hard time getting this installed. Seems to be a problem with python but every attempt to correct it has failed. Initially it was just telling me that gkeepapi was not installed, but everything I do to fix it (including trying to install gkeepapi independently of requirements.txt) seems to make it worse. Here’s where I stand now…hope someone can help.

The following happens whether I use pip or pip3:

kalico@MacBook-Air keep-it-markdown-0.4.3 % pip install -r requirements.txt 
Python path configuration:
  PYTHONHOME = (not set)
  PYTHONPATH = ':/Users/kalico/Library/Python/3.8/bin'

  environment = 1
  user site = 1
  import site = 1

  ]

I set the following in my .zhsrc

export PATH="${PATH}:/Users/kalico/Library/Python/3.8/bin"
export PYTHONPATH="${PYTHONPATH}:/Users/kalico/Library/Python/3.8/bin"

I’m assuming something is wrong with my Python setup but I’m not sure exactly what.
