Answer 1

您得到模块找不到错误，因为您没有添加您的应用程序安装在设置文件中的应用程序。

若要添加以下内容：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',

    'accounts',
    'users',
    'django_app', #added here
    'blog',
    'memberships',
    'dashboard',
    'crispy_forms',
    'bootstrap5',
