[PYTHON] What to do when the jupyterlab extension settings are not reflected

Introduction

I used this as a reference.

I was developing in a local environment such as pyenv, and when I installed and uninstalled it, the settings suddenly disappeared, and as I tried this and that, it worked, so I will leave a note here.

manner

I will delete two jupyterlab config files in my local environment.

~/.local/share/virtualenvs/projectname/share/jupyter/lab/settings/


build_config.json
page_config.json

I think it will work if you reinstall it.
