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  • Your current version of Yarn is out of date

Glad you got it worked out. Yes, JupyterLab requires nodejs to install extensions. The canvas error can be safely ignored, and our version of yarn will be updated in the next release.

Hi everyone,
How do I solve this problem if I'm not using conda, I'm using pip with Linux Mint

Any suggestion??

@pluviosilla Thank you so much!!! I was having an issue with trying to install Kite for Jupyter Notebook and tried to use a standalone installation of Node.js and that did not work
