当我运行 python3 prototypes.py build 时，我遇到了这个问题。我只想压缩css和js文件。这是我的设置。

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)

我跟着《轻量级 Django》这本书。

【解决方案1】：

根据Django documentation，NoArgsCommand 类现已弃用，将从 Django 1.10 中删除。请改用BaseCommand，默认情况下不接受任何参数。

这是你可以做的（我注释掉了旧方法供你参考）：

#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):
        ...

【解决方案2】：

试试这个，它在我的情况下工作。

try:
    from django.core.management.base import NoArgsCommand as BaseCommand
except ImportError:
    from django.core.management.base import BaseCommand


class Command(BaseCommand):
    """ 
    ABC
    def
    """

然后用你自己的实现编写你的类定义。

【解决方案3】：

试试这个，它在我的情况下工作。

pip install -U django-extensions

NoArgsCommand 已被弃用。只需更新库
