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
File "C:\Users\v-kangsa\AppData\Local\Continuum\anaconda3\lib\site-packages\notebook\__init__.py", line 25, in

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

aha got to update the jupyter_core and jupyter_client. Bad that anaconda navigator won't do it by default. :( — Santosh Kangane, Jan 21 '18 at 21:56

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

conda update jupyter_core jupyter_client

If you've installed jupyter using pip3.

pip3 install --upgrade jupyter_core jupyter_client

I get "Cannot uninstall 'jupyter-core'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall." – liyuan Dec 20 '18 at 02:21

I've met the same problem when I use ipython notebook .

After I tried upgrade jupyter, then I tried reinstall the ipython. The import error seem fixed.

pip3 uninstall ipython

pip3 install ipython

When I tried to install R the notebook was upgraded to 5.3.1 and same problem appeared, however the highest vote answer apparently didn't work for me.

What I did was:

conda uninstall jupyter notebook

then:

conda install jupyter notebook

and the problem solved with the old version.

I had a similar issue on Ubuntu after installing RStudio on my system. To solve it, first I tried @MichaelCara suggestion to update jupyter. However, after that I got the following new message error:

ImportError: libsodium.so.23: cannot open shared object file: No such file or directory

which I solved installing libsodium as explained here.

In short:

conda update jupyter_core jupyter_client jupyter_console
conda install libsodium

ImportError: cannot import name 'ensure_dir_exists'
