TypeError: Can't instantiate abstract class ScriptProvider with abstract methods get_resource_inst

我尝试把webdav.py 18行from .app import app改为from app import app，把出问题的配置'provider_mapping': {'/': ScriptProvider(app) }注释掉，并且修改下面的'domaincontroller': NeedAuthController(app) 为'http_authenticator':{'HTTPAuthenticator':NeedAuthController(app),}居然就可以了。。虽然还不知道为啥，mark一下

题主解决了吗？

虽然把出问题的程序注释掉能运行，但这根本是哪里的问题呢？

降级 wsgidav 版本成功解决
pip install wsgidav==2.4.1
如果还遇到cannot import name 'DispatcherMiddleware'
或者ImportError: cannot import name 'ContextVar' from 'werkzeug.local'
pip install flask==1.0
pip install werkzeug==0.16.1

由问题定位到代码所在 ...ScriptProvider(app)...
进而定位到类 ScriptProvider，class ScriptProvider(DAVProvider)
由继承关系，知其父类为 DAVProvider
根据问题的描述，可知ScriptProvider继承DAVProvider后，并没有实现其内部的抽象方法 get_resource_inst
再次回到 ScriptProvider类下观察其内部存在一个几乎同名的方法名 getResourceInst
经过替换 getResourceInst 为 get_resource_inst，成功解决问题

TypeError是类型错误，你传入的参数和函数定义的数据类型不匹配
