"@jupyterlab/toc" is not a valid npm package ??
I had to uninstall this for a minute since the most recent Conda packages clashed with toc's requirements a couple of weeks ago. I updated conda again today and thought I'd check to see if the dependencies had worked themselves out, but got this error message, instead.
I just had this happen. I downloaded the ZIP file and followed the instructions for the development install and it now works. Weird how this pops up again. At least we have a work around.

I met the same error as @b-gibbs , and have no idea to solve it. I'm using cnpm from Taobao NPM Mirror instead of the original npm because of some Internet connection policy. Commands responsed as follows:

See the log file for details: C:\Users\legen\AppData\Local\Temp\jupyterlab-debug-ie5zfrk4.log
I'm new to NodeJS and I have no idea how to solve this problem. Could you do me a favour?

Oh, the contents of the log files are as follows:

Maybe going back to Jupyter Notebook is a better choice ...
I was getting this error too with toc and other extensions. When I ran jupyter labextension install @jupyterlab/toc --debug I got the error EACCES: permission denied. As the output suggested, running sudo chown -R 1000:1000 "/home/rafael/.npm" did solve the issue for me.
If you're using an older version of jupyterlab you will need to pin the version of this extension. For instance, if you have jupyterlab 1.0, the latest version of this extension is 2.0.0. Otherwise, you'll get the same error as you see in this issue.
jupyter labextension install @jupyterlab/[email protected]
My problem was not having registered npm doing
`npm config set registry http://registry.npmjs.org/
jlpm config set registry https://registry.yarnpkg.com/`
