Dependecies issues during installation

[rtmlp]

Hi,

I installed JupyterLab and the first thing I tried to do is install your extension. But I am not able to do that due to the following errors.

I am not sure if that is related to any recent update at JL

Thanks

Hi @rtmatx, it looks like the version of JupyterLab you are using is an older one (0.31?). The most recent release of @jupyterlab/toc is for JupyterLab v0.34. I recommend either updating your JupyterLab, or downgrading @jupyterlab/toc to v0.1.0 (jupyter labextension install [email protected]).

Hi. Thanks for your quick comment. That helped. But I am receiving new error. Not sure if it is related to this extension though. Have you noticed these errors before

Hello! Currently running into a very similar error:

root@6e15fdbb6cbf:/scripts# jupyter labextension install @jupyterlab/toc Building jupyterlab assets An error occured. RuntimeError: npm dependencies failed to install See the log file for details: /tmp/jupyterlab-debug-s477h0h7.log

The log file is empty. My current version of jupyterlab is 1.0.0 (it was 1.1.3, but I downgraded based on advice found elsewhere on the internet, to no avail).

Do you have any suggestions? Thank you so much
