Hi,
I am tring to control LED connected to RPi by using python image.
In the folder I have Dockerfile:
FROM balenalib/raspberrypi3-fedora-python:latest
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
CMD [ "python", "./blink.py" ]
in the requirements.txt file i have one line:
RPi.GPIO
When i push i get this error:
