otree startapp AssertionError

#1 by Aysegul_Engin (edited )
Hi, 

I'm using oTree version 5.10.2 on MacOs Ventura with a Visual Studio Code. oTree is running in a separate virtual environment.

I created an otree app using the command otree startapp new. Seemingly I have broken something. Because after this I keep getting the error for any otree startapp command. 

Traceback (most recent call last):

AssertionError: Package 'new' could not be found, or maybe __init__.py is missing

Things I tried: 
* Uninstalling and reinstalling oTree in the virtual environment 
* Deleting the virtual environment completely and creating the environment and installing oTree from scratch 
* Deleting whole Python 3.11 installing Python 3.11.1 and setting up the whole environment and installing oTree again. 

None of these seem to help. I would appreciate any help please. 

kind regards,
