Is there a mismatch between your plist file and your weewx-venv/pyvenv.cfg
file ?
(my plist file)
<string>/Users/vince/weewx-venv/bin/python3</string>
<string>/Users/vince/weewx-venv/lib/python3.12/site-packages/weewxd.py</string>
<string>/Users/vince/weewx-data/weewx.conf</string>
(my weewx-venv/pyvenv.cfg file)
home = /opt/homebrew/opt/[email protected]/bin
include-system-site-packages = false
version = 3.12.3
executable =
/opt/homebrew/Cellar/[email protected]/3.12.3/Frameworks/Python.framework/Versions/3.12/bin/python3.12
command = /opt/homebrew/opt/[email protected]/bin/python3.12 -m venv
/Users/vince/weewx-venv
If they look similar with the python version agreeing between the files,
then I'm out of ideas. Sorry.
