python manage.py collectstatic error: cannot find rest_framework bootstrap.min.css.map (from book ‘Django for APIs’)

I am reading the book ‘Django for APIs’ from ‘William S. Vincent’ (current edition for Django 4.0)

In chapter 4, I cannot run successfully the command python manage.py collectstatic.

I get the following error:

Traceback (most recent call last):

whitenoise.storage.MissingFileError: The file 'rest_framework/css/bootstrap.min.css.map' could not be found with <whitenoise.storage.CompressedManifestStaticFilesStorage object at 0x102fa07f0>.

The CSS file 'rest_framework/css/bootstrap.min.css' references a file which could not be found:
  rest_framework/css/bootstrap.min.css.map

Please check the URL references in this CSS file, particularly any
relative paths which might be pointing to the wrong location. 

I have the exact same settings like in the book in settings.py:

STATIC_URL = "static/"
STATICFILES_DIRS = [BASE_DIR / "static"]  # new
STATIC_ROOT = BASE_DIR / "staticfiles"  # new
STATICFILES_STORAGE = "whitenoise.storage.CompressedManifestStaticFilesStorage"  # new

I couldn’t find any explanation for it. maybe someone can point me in the right direction.

Update: DRF 3.14.0 now supports Django 4.1. If you’ve added stubs to static as per below, be sure to remove them.

This appears to be related to Django 4.1: either downgrade to Django 4.0 or simply create the following empty files in one of your static directories:

static/rest_framework/css/bootstrap-theme.min.css.map
static/rest_framework/css/bootstrap.min.css.map

There’s a recent change to ManifestStaticFilesStorage where it now attempts to replace source maps with their hashed counterparts.

Django REST framework has only recently added the bootstrap css source maps but is not yet released.
