ImportError：无法导入名称“ ensure_dir_exists”

Question

我将Jupyter笔记本从旧版本更新为最新的5.3.1。但是，当我尝试从anaconda启动笔记本电脑时，它引发了导入错误：我尝试删除并安装Jupyter软件包，但问题仍然存在。

Traceback (most recent call last):
File "C:\Users\v-kangsa\AppData\Local\Continuum\anaconda3\Scripts\jupyter-notebook-script.py", line 6, in 
from notebook.notebookapp import main
File "C:\Users\v-kangsa\AppData\Local\Continuum\anaconda3\lib\site-packages\notebook\__init__.py", line 25, in 
from .nbextensions import install_nbextension

from jupyter_core.utils import ensure_dir_exists
ImportError: cannot import name 'ensure_dir_exists'

您需要从终端手动更新jupyter_core和jupyter_client：

conda update jupyter_core jupyter_client
