• upgrade to stretch (ideally need buster for python 3.7 and node 10)
• rebuilt python 3.7 (https://www.wyre-it.co.uk/blog/latestpython/)
  • the tests hung, re-started and finsihed the script manually
• install node 10 (https://www.w3schools.com/nodejs/nodejs_raspberrypi.asp) curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - sudo apt-get install -y nodejs
• pipenv (https://pipenv.readthedocs.io/en/latest/install/#installing-pipenv)
  • Need to really add pip3.7 to the path first to make this easier.
• install git (https://projects.raspberrypi.org/en/projects/getting-started-with-git/4) sudo apt install git
