File "/home/user/Escritorio/env/lib/python3.6/site-packages/bootstrap_select/widgets.py", line 1, in <module> from django.contrib.staticfiles.templatetags.staticfiles import static ModuleNotFoundError: No module named 'django.contrib.staticfiles.templatetags'

from django.templatetags.static import static
