django_vite: TypeError: expected str, bytes or os.PathLike object, not NoneType

Using Django Mystery Errors
1

I started a fresh Django 5.0.4 project and also did pip install django-vite

INSTALLED_APPS = [
    'django_vite',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # 'django_vite', # Tried here too instead
]

When I run the server I get TypeError: expected str, bytes or os.PathLike object, not NoneType

(Nothing else has been done to the project)

2

interesting, could you drop a screenshot/trace for what’s raising this?

Recreated this on my macOS Ventura having python 3.11 (the first post was from my Windows 11 laptop with python 3.10). Nothing else done except installed django_vite.
Same error(s).

I believe projects created with $ django-admin startproject don’t have a static folder setup by default…

can you make sure that’s set up correctly?

this seems to be using the STATIC_ROOT from you settings Path(settings.STATIC_ROOT), but is receiving a None instead

Ah…yes after I gave STATIC_ROOT = os.path.join(BASE_DIR, "static") in settings.py file its all good.
