已尝试操作 #

• 安装了databases包，但问题未解决

环境信息 #

• Python版本：Python 3.10.5
• INSTALLED_APPS配置：

INSTALLED_APPS = [
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
    "django.contrib.admindocs.urls",
    "rest",
    "rest_framework",
    "custom_db_logger",
]

从堆栈信息看，Python无法导入database模块，怀疑不是代码问题，求解决思路。
