Hello, I have some issues that need your help. I install the toc and run the 'jupyter lab build',and there is no error,but when I refresh the browser of the jupyter lab,i can't find the toc side bar,so it doen't work.

besides: my jupyter lab version is 2.0.1, python 3.7.6,could you help to check what is the problem of it?

Thanks!

I had the same problem.
I was using jupyter/datascience-notebook's docker image, and when I changed the tag to the old one, the toc sidebar appeared, maybe the latest version of jupyter lab doesn't support it.

I'm having the same problem with Jupyter 2.1.0.
I tried to remove Jupiterlab and reinstall, it didn't help.

I was having the same problem with Jupyter Lab v2.1.3. I uninstalled all extensions, ran jupyter lab clean --all, uninstalled and reinstalled jupyter through conda and that got it going.

You may have to uninstall/reinstall extensions & rebuild on launching.

This worked for me.

This worked for me too with my local environment. Thanks! Seems like an extension environment concern.
