Install from git failure

Description

Trying to currently install jupyterlab-deck from the git repository fails.

Reproduce

Short version:

pip  install git+https://github.com/deathbeds/jupyterlab-deck.git

Long version:

git clone git@github.com:deathbeds/jupyterlab-deck.git
cd jupyterlab_deck                                    
pip install .              
Processing /tmp/jupyterlab-deck
  Installing build dependencies ... done
  Getting requirements to build wheel ... error

  note: This error originates from a subprocess, and is likely not a problem with pip.

This seems to be caused by the following configuration in pyproject.toml

[tool.flit.external-data]
directory = "src/_d"

whereas there is no src/_d directory.

Is there some instruction to run first that would create that directory?

As mentioned in the readme, please see the contributing guide for a development setup description.

Hmm sorry @bollwyvl for the noise. That RTFM was well deserved: I got spoiled by these many Python package that can be installed directly from their git repo :-)

Alas, doit fails for me:

Any clue?
