pkg upgrade breaks app in Python venv
- Go to: [ bottom of page ] [ top of archives ] [ this month ]
Date: Mon, 11 Apr 2022 21:23:40 UTC
Hi all, I have had trytond (the server daemon from the www.tryton.org Tryton project) running in a Python venv without issue for several months, but on the weekend did a pkg upgrade and now trytond fails during startup due to what I take to be a library version dependency error related to libxml2.
Do modules in a venv need to be upgraded after a system pkg upgrade? Is there a standard workflow I should follow?
Thanks for any assistance.
