                Leon on Raspberry PI
              
          
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
