Background
I am trying to install some needed dependencies on a raspberry pi zero2w and am running into an issue with the adafruit bno055 library, specifically its dependency adafruit-blinka. Due to the nature of the project the pi can only connect to local non-internet network. For this reason I have pre-downloaded all the libraries and dependencies through pip as .tar.gz files, as well all the setuptools and wheel .whl files. I then install them on the offline device.
Issue
I am running into the problem where I get module board not found after import board which is a required library in order to create an I2C connection in python
What I have tried
After looking at some other posts a common solution seems to be running the command
sudo python3 pip install --force-reinstall adafruit-blinka
for my case using source files I have tried both
sudo python3 -m pip install --force-reinstall adafruit-blinka --no-index --find-links lib/
pip3 install --force-reinstall adafruit-blinka --no-index --find-links lib/
as well as using the package name directly Adafruit-Blinka-7.2.0.tar.gz
these commands have mixed results, the majority of the time the command stalls for a long period of time on Running command python setup.py egg_info then errors with python setup.py egg_info failed with error code 1 and the one time it successfully reinstalled the package it still failed to import board
