ImportError: cannot import name 'ensure_dir_exists'

Question

I update the Jupyter notebook from the old version to latest 5.3.1. However, when I try to launch the notebook from anaconda, it throws an import error: I tried to remove and install Jupyter package, still, the issue persists.

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

ImportError: cannot import name 'ensure_dir_exists'

Answer 1

You need to update jupyter_core and jupyter_client manually from your terminal:

conda update jupyter_core jupyter_client

Answer 2

If you've installed jupyter using pip3.

pip3 install --upgrade jupyter_core jupyter_client

Answer 3

update jupyter core

pip install jupyter-core --upgrade

this working for me in Anaconda3 with python 3.6
