I wanted to upgrade my system image from fishandchips to haggis. I'm running python 3.8 on both. Flask no longer works. As part of the troubleshooting, I thought I'd investigate the packages with pip3, however, all pip3 calls from the console results in the following (sorry for formatting):

14:50 ~ $ pip3 --version

SyntaxError: invalid syntax

That looks like you have somehow installed broken packages into your .local diretory. Delete ~/.local/lib/python3.8 and everything should work again.

I was finally able to implement the fix, and I wanted to report that this indeed did work. Thank you very much!

Thanks for letting us know!
