[Artur Basiak (artur-basiak)]

The problem is with pypa/setuptools project. Please see: https://github.com/pypa/setuptools/pull/1043

[Laurent DURAND (ldurand)]

I've faced a similar issue using DevStack :
2017-06-01 09:50:53.725 | import six
2017-06-01 09:50:53.725 | ImportError: No module named six

I've solved this issue using following command :
$ /opt/stack/requirements/.venv/bin/pip install six

Then I've restarted stack.sh and it's OK.

Workaround from Laurent worked for me

[Sam Wan (sam-wan)]

This issue has been fixed in upstream pypa/setuptools.
