Hello @danieleades,

I'm not able to reproduce it.

Looks like your poetry is installed via the deprecated get-poetry.py script. I would recommend uninstalling Poetry and reinstall via install-poetry.py.

using the new installer solves it

Hi, I just installed using install-poetry,py script and still having the same issue.

  ModuleNotFoundError

  No module named 'virtualenv.activation.xonsh'

  at <frozen importlib._bootstrap>:973 in _find_and_load_unlocked

Any idea?

[christopherpickering]

Doing pip uninstall virtualenv in the base python env that poetry is using seems to fix this.

For future reference - this also fixed this issue for me in Windows 10 environment
