本文详细解析了在启动Django项目时遇到的RuntimeError错误，该错误源于模型类未声明明确的app_label且对应的app未在settings.py的INSTALLED_APPS中注册。文章提供了具体的解决方案，即如何在settings.py中正确添加app包名称。

启动django 时，报错如下：
RuntimeError: Model class addresstest.models.address_info doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

需要在 settings.py 中的INSTALLED_APPS 添加 app包名称： addresstest

解决方案：

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