I'm unable to reproduce this

The traitlets error I was able to reproduce though:

(ins)efraim@3900XT ~/workspace/guix$ guix environment --ad-hoc python python-traitlets -- python3 -c 'import traitlets'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/gnu/store/3zwlgb58b6wca49yk9hjpz90s12crgid-profile/lib/python3.8/site-packages/traitlets/__init__.py", line 1, in <module>
    from .traitlets import *
  File "/gnu/store/3zwlgb58b6wca49yk9hjpz90s12crgid-profile/lib/python3.8/site-packages/traitlets/traitlets.py", line 57, in <module>
    import six
ModuleNotFoundError: No module named 'six'

I fixed that by adding python-six as a propagated-input to
python-traitlets. So in any case go ahead and run `guix pull` again and
try again, it should be working now.
