Python django:在/admin/login/处出现操作错误，无法打开数据库文件

我在iis6中部署了django项目。当我使用超级用户名和密码登录管理页面时，会产生如下错误：

这是我的设置.py

enter code here
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': 'C:\\inetpub\\wwwroot\\untitled5\\db\\db.sqlite3',
    }
}

我试图更改数据库文件的权限，但它就是不起作用。

在数据库文件路径中使用斜杠而不是反斜杠。

数据库={'default'：{'ENGINE'：'django.db.backends.sqlite3'，'NAME'：'C:/inetpub/wwwroot/untitled5/db/db.sqlite'，}}我这样更改它，仍然不起作用
