I'm trying to install Flask to RPi Bullseye OS on a Pi3 . A lot of packages I try and install or update come back with the same general error that "cpython" is invalid.
I'm sure the issue is self inflicted. What is the best way to fix this, uninstall and reinstall python perhaps.
Help appreciated!
Code:
@raspberrypi:~ $ python -m pip install --upgrade pipDefaulting to user installation because normal site-packages is not writeableLooking in indexes: https://pypi.org/simple, https://www.piwheels.org/simpleRequirement already satisfied: pip in ./.local/lib/python3.9/site-packages (25.2)WARNING: Error parsing dependencies of pyzmq: Invalid version: 'cpython'Help appreciated!
