我在Pycharm上使用Jupyter Notebook的时候，发现无法正常使用，Jupyter Server无法正常拉起来。

![在这里插入图片描述][384284c606194e079847e8108afd309a.png]  
具体的报错为：

File "C:\Users\chgagnon\AppData\Roaming\Python\Python38\site-packages\notebook\traittypes.py", line 235, in _resolve_classes
        klass = self._resolve_string(klass)
      File "C:\Users\chgagnon\AppData\Roaming\Python\Python38\site-packages\traitlets\traitlets.py", line 2009, in _resolve_string
        return import_item(string)
      File "C:\Users\chgagnon\AppData\Roaming\Python\Python38\site-packages\traitlets\utils\importstring.py", line 30, in import_item
        module = __import__(package, fromlist=[obj])
    ModuleNotFoundError: No module named 'jupyter_server.contents'

当我在终端中运行时，我也遇到了同样的错误。`jupyter notebook`

降级到版本也可以在我的情况下修复它：

conda install traitlets==5.9.0 -c conda-forge

这样之后，便可以顺利使用！
