In my virtualenv activation, I like to set export PYTHONPATH=<mypath> so that I can run scripts directly.
Now when I run tox from within the virtualenv, I get the following warning in alarming red color:
WARNING: Discarding $PYTHONPATH from environment, to override specify PYTHONPATH in 'passenv' in your configuration.
I do understand the warning and I am fine with tox overriding PYTHONPATH, but the warning is annoying. I could leave the venv and run tox without it, but that is also annoying.
Is it a good idea to explicitely zero PYTHONPATH="" when running tox?
[testenv]
# Explicitely reset pythonpath to avoid the "discarding" warning
setenv = PYTHONPATH = ""
Does this affect other things which tox may want to do with the path, which I am not aware about yet?
