NodeJs 5+ error when installing jupyterlab-toc

This error may well look as mysterious to you as it does to me, but I’ll post it just in case someone might be able to clue me in.

> jupyter labextension install jupyterlab-toc

Errored, use --debug for full output:
ValueError: Please install nodejs 5+ and npm before continuing. nodejs may be installed using conda or directly from the nodejs website.

Many of us a delighted you did this (THANKS!). Do you have any plans to add conda support?

Never mind. Installing nodejs with

conda install nodejs

fixed the problem. I’m still getting a few errors, notably:

• jupyter\lab\staging\node_modules\canvas: Command failed
• Your current version of Yarn is out of date

maybe “pip install nodejs”
