About that, I dealt with that for a test installation if
jupyterhub/jupyterlab i am working in at my university.
My solution consisted in two parts:
1) Copying the threejs files to a directory where the jupyterhub server can
serve them (in my case, it was /usr/local/share/jupyterhub/static/ )
2) Patching sage to look for those files in the new addresses
The relevant part of my patch is:
diff --git a/src/sage/repl/rich_output/backend_ipython.py b/src/sage/repl/
rich_output/backend_ipython.py
index 5085c3d..8f93d06 100644
