Plotly ext install hanging up on package resolution about jupyter-renderers

[jwhendy]

Dammit. I just searched on and off all day for incantations of "jupyterlab extension install hangs" and similar and didn't see this. I guess I should have checked here first, but assumed it was a fringe/unique problem.

I've got the exact same issue. Looks like this indefinitely when I try to install:

$ jupyter labextension install @jupyterlab/plotly-extension
> /usr/bin/npm pack @jupyterlab/plotly-extension

I have tried this on 2 different machines (My work Mac and home PC, both using Anaconda distro) and getting the same results.

Can you try @realjumy's solution: #132

[gnestor]

I am able to reproduce this using Node 10. Downgrading to Node 9 fixes the "hang on resolving packages step of yarn install".

[jwhendy]

The install works for me using Node 9 as well. On arch, I downgraded to 2018-03 versions from the Arch Linux Archive:

• icu from core
• nodejs from community

[dvandagriff]

Downgraded to node 6 using Brew from #132 and it worked with no issues. Thank!!!

[gnestor]

Good to hear!

[jwhendy]

Can I clarify that this is closed because it's a duplicate of #132? (Not that I need to re-downgrade the default nodejs version indefinitely?) :)
