Just installed, my project is in Python and I'm getting ModuleNotFoundError

I’ve just installed Cursor but I cannot run anything on the terminal because the python modules don’t seem to be installed:

I found this person who seems to be experiencing the same: [Linux] Cannot use python scripts both in cursor IDE and Cursor Terminal : working command in system terminal does not work in cursor terminal, executable "sys.executable: /opt/cursor.appimage" replaces selected Python executable and blocks module imports · Issue #1484 · getcursor/cursor · GitHub

Thanks

Same here

I have the same issue. Opened my project in Cursor, when I try to run it:

.venv mho@tuxedo: ~/Projects/dns-admin/src$ python manage.py runserver
Traceback (most recent call last):
  File "/home/mho/Projects/dns-admin/src/manage.py", line 11, in main
    from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/mho/Projects/dns-admin/src/manage.py", line 22, in <module>
    main()
    ~~~~^^
  File "/home/mho/Projects/dns-admin/src/manage.py", line 13, in main
    raise ImportError(
    ...<3 lines>...
    ) from exc

I have no problems running it in VS Code.
Tried recreating the VENV in Cursor, no difference.

Could this be a Linux thing? Does running Cursor as an AppImage mess up some Python stuff?

I tested some more. It seems to be an issue with zsh. If I change the terminal to bash, it works fine.
