ValueError: "@kaggle/jupyterlab" is not a valid npm package
Hi,
I found your extension through this article: https://www.kaggle.com/product-feedback/117903.
By launching jupyter labextension install @kaggle/jupyterlab, I was not able to install this jupyterlab extension, I get the error: ValueError: "@kaggle/jupyterlab" is not a valid npm package.
This was the full error log:

I saw that the above nodejs version was rather low though, so I deinstalled it and installed nodejs from the conda-forge channel, but then again got the same error.
Full log of that:

I also can't find the extension when I browse manually through the extension tab on the left on JupyterLab's GUI, nor can I find your package manually in the npm package repository (https://www.npmjs.com/search?q=kaggle).
Could it be that this extension has been discontinued? It looked like a nice idea to me though.
Kind regards.
Problems installing - nodejs
hi there,
im new to jupyter - and wanted to use kaggle for my first tryouts.
But when i want to install the extension (ubuntu20.04, miniforge installed, jupyterlab (and ir-kernel) from conda-forge) i get the error:
jupyter labextension install @kaggle/jupyterlab
An error occured.
ValueError: Please install Node.js and npm before continuing installation. You may be able to install Node.js from your package manager, from conda, or directly from the Node.js website (https://nodejs.org).
See the log file for details: /tmp/jupyterlab-debug-7746_i0p.log
So i install nodejs from conda https://anaconda.org/anaconda/nodejs
After the same error appears.
I also tried nodejs from conda-forge (https://anaconda.org/conda-forge/nodejs)
Still the same error when i want to
jupyter labextension install @kaggle/jupyterlab
The log says:
