Problems installing - nodejs

[kaktux]

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:

Node v10.19.0
