I have a python test suite running with tox and since this morning test suite do not run any longer and return the following error. AttributeError: module 'virtualenv.create.via_global_ref.builtin.cpython.mac_os' has no attribute 'CPython3macOsFramework' I did try to fix python, tox and virtualenv…

I just found out that the problem is with tox 3.14.5 and CircleCI. Setting tox = "!=3.14.5 in project dependencies resolves the issue on CircleCI.

Python tox doesn't build anymore
