When I run python3 prototypes.py build i got this problem. i just want to compressor the css and js file. and this is my setting.

import os
import sys
from django.conf import settings


BASE_DIR = os.path.dirname(__file__)

settings.configure(
   DEBUG=True,
   SECRET_KEY='plasq@qb+&t-@=x56@=ss=+y-4kp*hj1wy5p!+$cinzhnd+erb',
   ROOT_URLCONF='sitebuilder.urls',
   MIDDLEWARE_CLASSES=(),
   INSTALLED_APPS=(
       'django.contrib.staticfiles',
       'sitebuilder',
       'compressor',
    ),

TEMPLATES=(
    {
        'BACKEND':'django.template.backends.django.DjangoTemplates',
        'DIRS':[],
        'APP_DIRS':True,
    },
),
STATIC_URL='/static/',
SITE_PAGES_DIRECTORY=os.path.join( BASE_DIR,'pages'),
SITE_OUTPUT_DIRECTORY=os.path.join( BASE_DIR,'_build'),

STATIC_ROOT=os.path.join( BASE_DIR,'_build','static'),
STATICFILES_FINDERS=(
                     'django.contrib.staticfiles.finders.FileSystemFinder',
                     'django.contrib.staticfiles.finders.AppDirectoriesFinder',
                     'compressor.finders.CompressorFinder',
                     )
    )
if __name__=="__main__":
     from django.core.management import execute_from_command_line
execute_from_command_line(sys.argv)

I followed the book "Lightweight Django".

Answer 1

According to Django documentation, the class NoArgsCommand is now deprecated and will be removed from Django 1.10. Use BaseCommand instead, which takes no arguments by default.

Here is 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):
        ...

Answer 2

Try this, its working 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.
