Install dependencies process fails

[netdudeuk]

Using latest version of Raspbian Buster (2019-09-26-raspbian-buster-lite), the documented process for installing the dependencies fails with -

Could not find a version that satisfies the requirement astroid==2.2.5 (from -r requirements.txt (line 2)) (from versions: 1.0.0, 1.0.1, 1.1.0, 1.1.1, 1.2.0, 1.2.1, 1.3.0, 1.3.1, 1.3.2, 1.3.3, 1.3.4, 1.3.5, 1.3.6, 1.3.7, 1.3.8, 1.4.0, 1.4.1, 1.4.2, 1.4.3, 1.4.4, 1.4.5, 1.4.6, 1.4.7, 1.4.8, 1.4.9, 1.5.0, 1.5.1, 1.5.2, 1.5.3, 1.6.0, 1.6.1, 1.6.2, 1.6.3, 1.6.4, 1.6.5, 1.6.6, 2.0.0.dev0, 2.0.0.dev1, 2.0.0.dev2, 2.0.0.dev3, 2.0.0.dev4)

using stretch

I created an updated requirements.txt and used the following commands to get mine working -

pip3 install -r requirements.txt
python3 ./src/main.py --display ssd1322 --width 256 --height 64 --interface spi

I cannot promise that this is good for everyone though.

I wanted the better font scaling so I then cloned a fork of the project as shown below and did some tidying up as shown below -

git clone https://github.com/balena-io-playground/UK-Train-Departure-Display.git
cd UK-Train-Departure-Display
cp /home/pi/train-departure-screen/config.json .
rm balena-run.sh
rm Dockerfile.template
rm requirements.txt
rm config.sample.json

python3 ./src/main.py --display ssd1322 --width 256 --height 64 --interface spi

I did get the balenaCloud version working without any issues but preferred to have more local control.

requirements.txt

pip3 install -r requirements.txt
