Hello,
I'm trying to install Python Spidev on a RPi 4 Alpine Linux Edge OS; my
current Alpine Linux Release is VERSION_ID=3.16.0_alpha20220328.
Using this command pip install spidev for Python Spidev installation
fails with this error:
Defaulting to user installation because normal site-packages is not
writeable
