Jupyter latest version crashes when installing with conda

[willgdjones]

Going to repost here as there seems to be more activity.

The most recent release of jupyter seems to have some library linking issues.

After a clean install of anaconda, and conda create -n test jupyter

then

jupyter notebook

gives me

Thanks in advance!

This wouldn't be related to Jupyter, but one of its dependencies. What do you see in conda list?

[minrk]

Since this is an issue with the conda libzmq package not loading its dependency properly, it is possible that conda install libsodium would fix it, or perhaps remove and reinstall zeromq:

conda remove zeromq
conda install zeromq

[willgdjones]

Hi @minrk

conda remove zeromq; conda install zeromq

worked a charm. Thanks for your help! This seems to be an eq fix of 'turning it off and on again' so I should have thought of that earlier.

Had the same issue with libzmq.5.dylib

remove/install worked

[yitong239]

had the same issue, after i set the environment with conda, the jupyter notebook cannot launch by itself. remove / install worked, that is great~ thanks

[chufuxi]

same issue, thanks for advice

[CommonClimate]

same issue, same solution. Grateful for this thread!

Just to add to this, just uninstall zeromq by conda uninstall zeromq --force did not work. I had to fully uninstall:

>>> conda uninstall zeromq
    ipykernel:           4.8.2-py36_0          conda-forge
    ipympl:              0.2.1-py36_0          conda-forge

    ipywidgets:          7.0.1-py_2            conda-forge

    zeromq:              4.2.5-hfc679d8_3      conda-forge

followed by a reinstall of the above.

I have updated zeromq from the Anaconda Navigator and the issue was resolved on a Mac iOS High Sierra 10.13.6.

[caitaozhan]

Same issue. The following solution worked for me.

conda install libsodium

[Autoom]

same issue, conda remove zeromq # step1 conda install zeromq #step2 conda install notebook #step3
