我得到这个错误，我找不到是什么原因造成的。以下是回溯：

ModuleNotFoundError: No module named 'apps.product.context_processors'

我的核心/views.py是：

from django.shortcuts import render

from apps.product.models import Product

def frontpage(request):
    newest_products = Product.objects.all()[0:8]

    return render(request, 'core/frontpage.html', {'newest_products': newest_products})

def contact(request):
    return render(request, 'core/contact.html')

我的context\u processors.py是：

from apps.product.models import Category

def menu_categories(request):
    categories = Category.objects.all()

    return {'menu_categories': categories}

应用程序目录结构为：

以及核心和产品应用程序文件夹结构的详细信息：

我应该补充一点，由于我正在使用django的旧版本（但在设置项目时没有明确说明）的教程，我不得不对apps.py文件进行一些更改，以便让它查找应用程序。我怀疑这可能是问题的原因，但我不知道如何解决它。我的核心/apps.py文件：

from django.apps import AppConfig

class CoreConfig(AppConfig):
    #default_auto_field = 'django.db.models.BigAutoField'
    name = 'apps.core'

和product.apps.py：

from django.apps import AppConfig

class ProductConfig(AppConfig):
    #default_auto_field = 'django.db.models.BigAutoField'
    name = 'apps.product'

我希望我已经提出了正确的信息，如果有人可以帮助我与这个具体问题，我将不胜感激。
