6 months ago Are there any steps to prepare tox (except installing it) that are not documented somewhere and I might have missed?
$ tox -e test

I might have found a hot trail. Totally independent from tox and pydoctor I accidentally observed a similar error using hatch to create a virtual environment. The error output of hatch (see below) is bit easier to read so I realized the problem is about the package virtualenv. I uninstalled it via python3 -m pip uninstall virtuelenv. Then hatch worked.
Then I tried tox on pydoctor. And it worked.
I am not enough into the details about virtual environments or the package virtuelenv. So I am not able to decide where and if I should open a bug report. Maybe related to https://github.com/pypa/virtualenv/issues/2551. Maybe I encountered the first time a real use case why I should use virtual environments. Currently I do avoid them as much as possible. I am a but stubborn about this topic. :smile:

I guess what is missing in the contributors docu is how to install pydoctor for developers (e.g. "python3 -m pip install -e ."). And why is there a "mac_os" in this output? I do run these tests on Debian 11 on an AMD64.
