Hello gurus,
I’ve had success getting Node.js working on various projects. Today, I hope to get CircuitPython installed and running for a GPIO project where most of the support/examples are centered around CircuitPython.
After looking at different examples, I’m getting stuck on the build. Any ideas of what I’m missing?:
Device: Raspberry Pi 4
Desired Python version: 3
Pip/pip3 could benefit from an upgrade
Here’s the current work-in-progress:
# Initial reference: https://github.com/balena-io-examples/balena-python-hello-world
FROM balenalib/%%BALENA_MACHINE_NAME%%-python:3-stretch-run
# Set our working directory
WORKDIR /usr/src/app
# Read: https://gallaugher.com/makersnack-installing-circuitpython-on-a-raspberry-pi/
# RUN install_packages python-smbus i2c-tools python3-pip
# TODO: Hmm. With this disabled, now I'm getting too many request errors. Will try again later?
# "toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit"
# Also, python3-pip may not be required here?
# upgrade pip
# TODO: This fails for now, attempting to run without (may not be required)
# RUN python -m pip install --upgrade pip
# Copy requirements.txt first for better cache on later pushes
COPY requirements.txt requirements.txt
# pip install python deps from requirements.txt on the resin.io build server
RUN pip install -r requirements.txt
# This will copy all files in our root to the working directory in the container
COPY . ./
# Enable udevd so that plugged dynamic hardware devices show up in our container.
ENV UDEV=1
# main.py will run when container starts up on the device
CMD ["python","-u","src/main.py"]
requirements.txt if needed:
RPI.GPIO

From this I’ve been experiencing two errors. My latest has been a toomanyrequests error. Maybe I’m building too often as I figure this out?
Previously (commented out) I was failing in upgrading pip. Maybe there’s a different command for that in build?
Thanks for taking a look in advance! My familiarity with Python in general is limited, yet I look forward to giving it a shot on a Pi for GPIO purposes.
