PermissionError for nbextensions on startup with v1.29+

hi all, i've been trying out solara for the past month or so. i was using v1.28 with no issues. today i tried upgrading and i've been having trouble getting things running on any higher version.

i know that there were significant changes to the packaging starting with v1.31, but at this point i can't even upgrade to v1.29. i'm getting a

PermissionError

PermissionError

on startup:

PermissionError: [Errno 13] Permission denied: '/usr/local/share/jupyter/nbextensions/jupyter-vuetify/extension.js'

PermissionError: [Errno 13] Permission denied: '/usr/local/share/jupyter/nbextensions/jupyter-vuetify/extension.js'

i'm creating a multi-page app, and i'm pip-installing in editable mode (since i'm actively developing) from a pyproject.toml file. i have an environment with solara v1.28.0 and one with v1.29.1. it works with v1.28, but i get the error with v1.29 (and v1.30).

any help would be appreciated!

i've diffed the outputs from for my two environments, and the only difference is the version of solara (and solara-assets).

i can create an issue in GitHub if that's more appropriate.

i think maybe this change is the culprit.

I just created this issue for this.

<:issue_open:882464248951877682> [widgetti/solara] PermissionError for nbextensions on startup with v1.29+

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'

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:

i think i have resolved my issue -- by chmod-ing my directory to allow more access than was initially present. however, i mentioned in the issue that i raised that the path that was causing trouble did not even exist. so i wonder if the code could be improved by catching

PermissionError

PermissionError

s -- if the user doesn't have permission to the directory or file, that is basically the same as "does not exist".
