折腾了一天没有解决：开始以为是iis问题，但是看到代码已经是网页报错了，而且好像是数据库问题，关键是数据库还是原来的数据库，都是一样的代码，就是部署到iis不能使用。后来参考了https://blog.csdn.net/qq_45652065/article/details/109704758的文章将settings里的

代码语言：javascript复制

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

改为：

代码语言：javascript复制

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': str(os.path.join(BASE_DIR, "db.sqlite3")),
    }
}

解决问题，回头看django 2.2版本的settings中确实也是这么写的，不明白为什么到3.0更改并且不能正常运行

记录一下。帮助爬坑
