PermissionError for nbextensions on startup with v1.29+ #611
Description
I'm getting the following error when attempting to run Solara with version 1.29+:
PermissionError: [Errno 13] Permission denied: '/usr/local/share/jupyter/nbextensions/jupyter-vuetify/extension.js'
Everything works fine on 1.28.0 though. I started a thread in the discord questions channel, but it seems like an issue might be more appropriate.
This is the logging output with the stacktrace:

It looks like it is related to this change, though whether that change is the cause or simply exposed the issue, I do not know.
