Tell us what’s happening:
Hello, have few problems and can’t solve it by myself.
Few days ago I finished my first project (Time calculator), I did not have any issues with replit and everything went fine.
However, yesterday I started a new challenge (Arithmetic Formatter) and everything went wrong from the beginning.
Firstly, I got ModuleNotFoundError: No module named ‘pytest’. I tried to change the nix file. Unfortunately, it did not help me.
Then I got another problem, Use run command is gone and I don’t know how to return it.
Thank you for your help
