Cannot run `jupyter lab build` with ipyvuetify install in jupyterlab 4.X

[jabbera]

Note: I recognize this isn't required for ipvuetify, this is blocking me with another extension.

python3.11 -m venv .venv
source .venv/bin/activate
pip install "jupyterlab==4.0.0" "ipyvuetify==1.10.0" # jupyterlab 4.3 doesn't work either.
jupyter lab build

Yields the error:

looks like someone else ran into this:

Can you try if deleting .../your_env/share/jupyter/lab/extensions/jupyter-vue-1.11.2.tgz fixes it?

[jabbera]

The build works after doing that. I'll need to verify behavior. What exactly is that doing?

omg, same issue, same fix for me right now.
