New issue by tornaria on void-packages repository

https://github.com/void-linux/void-packages/issues/35341

Description:
### Steps to reproduce the behavior

1. install package `jupyterlab`
2. run `jupyter-lab` in a terminal (as a regular user fwiw)
3. an error pops up both in the terminal and in a browser:
```
[E 2022-02-01 09:38:05.353 LabApp] JupyterLab application assets not found in "/usr/share/jupyter/lab"
[E 2022-02-01 09:38:05.353 LabApp] Please run `jupyter lab build` or use a different app directory
```

I was able to workaround by creating my own app directory as follows:
```
$ mkdir ~/lab
$ jupyter lab build --app-dir=~/lab
```
and then run jupyter lab as
```
$ jupyter lab --app-dir=~/lab
```

Beware: this will take some time and bring up (download I guess?) ~400M of nodejs stuff. I'm not sure one would want to ship that inside the xbps, maybe give some warning or instructions to the user?
