TypeError：“方法”對象不支持項目分配

Question

為雜貨店應用程序設置登錄/注冊頁面，我繼續收到此錯誤。

“TypeError：‘方法’對象不支持項目分配”

每當我嘗試運行服務器並刷新登錄頁面時都會發生這種情況，以便查看它是否有效。

示例代碼：（這是來自我的 manage.py 文件）

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys


def main():
    """Run administrative tasks."""
    os.environ.setdefault['DJANGO_SETTINGS_MODULE']='groceryshop.settings'
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()

示例代碼：settings.py（終端繼續說我的應用程序已卸載）

import os
from pathlib import Path

from userprofile.models import UserProfile
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent


# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/4.0/howto/deployment/checklist/

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = 'django-insecure-pw7g8*-80b!900@na(cjpgp21nr784-0aawklg8!br#cel2!@h'

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = False

ALLOWED_HOSTS = []


# Application definition

INSTALLED_APPS = [
    'userprofile',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'allauth',
    'allauth.account',
    'allauth.socialaccount',

]

獲取任何/所有幫助。 <3

此行不正確，因為os.environ.setdefault是一種方法，但您嘗試將其用作類似 dict 的對象。

os.environ.setdefault['DJANGO_SETTINGS_MODULE']='groceryshop.settings'

相反，您應該這樣做：

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'groceryshop.settings')

供您參考，dict.setdefault的文檔鏈接。
