Python ModuleNotFoundError：没有名为jupyter_server.Contents'；的模块

我收到了这样的错误:

Traceback (most recent call last):
File "C:\ProgramData\anaconda3\Lib\site-packages\notebook\traittypes.py", line 235, in _resolve_classes
klass = self._resolve_string(klass)
^^^^^^^^^^^^^^^^^^^^^^^^^^^

module = __import__(package, fromlist=[obj])
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'jupyter_server.contents'

During handling of the above exception, another exception occurred:

感谢您的帮助！:)

我试过安装和卸载，但都不起作用.
