Can not use in JupyterLite

[sunzhuo]

I runned folowing cells in JupyterLite:

%pip install pythreejs

from pythreejs import *
from IPython.display import display
from math import pi
# Reduce repo churn for examples with embedded state:
from pythreejs._example_helper import use_example_model_ids
use_example_model_ids()
BoxGeometry(
    width=5,
    height=10,
    depth=15,
    widthSegments=5,
    heightSegments=10,
    depthSegments=15)

And get these error messages:

Hello @sunzhuo, This sounds like the same issue as #389.

In Jupyterlite, this problem can stem from too few packages being present in the python environment at build time. Try changing your requirements.txt to the requirements.txt of this project: https://github.com/triadtitans/rigid_body_interactive
