ImportError: cannot import name 'NoArgsCommand'
When I run python3 prototypes.py build I got this problem. I just want a compressor css and js file. and this is my setup.
import os
import sys
from django.conf import settings
BASE_DIR = os.path.dirname(__file__)
settings.configure(

According to the Django doc ( https://docs.djangoproject.com/en/1.11/releases/1.8/ ) the class is NoArgsCommand
now deprecated and will be removed in Django 1.10. Use instead BaseCommand
, which takes no arguments by default.
Here's what you can do (I commented out the old way for your reference):
#from django.core.management.base import NoArgsCommand
from django.core.management.base import BaseCommand
#class Command(NoArgsCommand):
class Command(BaseCommand):
#def handle_noargs(self, **options):
def handle(self, *args, **options):
...

Try it, it works in my case.
try:
from django.core.management.base import NoArgsCommand as BaseCommand
except ImportError:
from django.core.management.base import BaseCommand
class Command(BaseCommand):
"""
ABC
def
"""
Then write your class definition with your own implementation.
