How to work with npm from guix shell

[Roland Everaert via <help-guix@gnu.org>]

Hello,

I try to install the community server of the solid project using the following documentation in a guix shell session.

https://solidproject.org//self-hosting/css

Unfortunatelly I got the following error during the execution of 'npm install -g @solid/community-server'

Command use to start the guix shell session.

guix shell -CN node

I am totally illiterate about node.js and its ecosystem. So, how to setup a proper environment for running node.js application with guix shell or guix in general?

I am running the application in a guix shell session for testing purposes.
