The installation hangs at resolving jupyterlab_bokeh package about jupyter_bokeh

[fabikw]

I've encountered the same problem. I'm using nodejs v10.0.0 if it matters.

This problem started happening on my machine recently as well. I'm running Windows 10.

I got the same problem with nodejs v10.2.0.
After downgrading nodejs to v9.11.1, I've solved the problem.

Same problem here with node 10.2.0. downgrading per @akiraakaishi also worked for me

[shenker]

Downgrading nodejs from v10.5.0 to v9.11.2 also fixed this problem for me (on linux-64).

Same problem here. A quick tip on how to downgrade nodejs with conda :
conda install -c conda-forge nodejs=9.11.1

This issue is an upstream problem with JupyterLab (jupyterlab/jupyterlab#4986), so I'm going to mark as closed.

If jupyterlab begins to support node@10 and there's a problem with this extension, please reopen this issue.

Thanks for opening the issue!

Following the link above jupyterlab seems to have added the necessary support for nodejs 10, and this issue was resolved for me by upgrading jupyterlab.
