Hi Francis,

If you ran firedrake-update with PYTHONPATH set then it's possible six was found in your PYTHONPATH and therefore not installed by the upgrade script. Once you unset PYTHONPATH then it would not be found.

Try rerunning firedrake-install with PYTHONPATH unset so hopefully six will get installed

(six is the Python 2 to 3 compatibility module)

Regards,

David

Minor correction.

I remembered from previous installations that I should clear my PYTHONPATH before starting firedrake. I did that and then got a slightly different error.

>>> import firedrake

Traceback (most recent call last):

from six.moves import zip

ImportError: No module named six.moves

It can import petsc4y and other stuff, just not sure what six.moves is and why the module is not found.
