Initially, solving the exercises locally worked fine but recently I keep getting an error. Testing still works fine on the on the others I had done before but not on any new downloaded exercises. Any help will be greatly appreciated. Following is the error message from Ellen’s Alien game.

Here is the command.

python3 -m pytest -o markers=task classes_test.py

and here is my code.

"""Solution to Ellen's Alien Game exercise."""


class Alien:

    -------

I created a repository if it may be of more help.

My gut reaction here is that your Python venv got messed up somehow. It might be worth deleting it and setting it back up and seeing if that helps. That error isn’t related to any of the Exercism files.

Ok will do, thanks a lot hey.
