ModuleNotFoundError：没有名为“jupyter_core”的模块

Question

I am using a windows machine to start Jupyter notebook server on a virtual Ubuntu 16.04. I expect a URL as an output which I can paste in inte.net browser and run a.ipynb file. jupyter notebook --ip 0.0.0.0 is producing the following error after I have upgraded Python to 3.7.

*(Earlier to upgradation, the jupyter notebook was working fine)

pkj_admin@ip-50-60-0-75:~$  jupyter notebook --ip 0.0.0.0    
Traceback (most recent call last):
  File "/usr/local/bin/jupyter", line 5, in <module>
    from jupyter_core.command import main
ModuleNotFoundError: No module named 'jupyter_core'

Thanks

Answer 1

I too faced this issue. I solved it using:

pip3 install jupyter

Answer 2

This worked for me

sudo apt install python3-jupyter-core

Answer 3

This is a very common issue with jupyter notebook. It says jupyter_core not found with current installation packages. It is messed up with paths.

jupyter_core might be installed locally but it is looking at root or sys python version. Try to uninstall there and reinstall jupyter .

>> python -m pip uninstall jupyter-core;python -m pip uninstall jupyter;

# inside conda env or similar env
>> pip uninstall jupyter
>> pip install jupyter
