snippets manager keeps leftover trash after being uninstalled... Cannot get rid of errors from Elyra days...

[richlysakowski]

Describe the bug

I want to love this extension, but its still got Elyra disease. The first time I ever installed it in the original Elyra format it corrupted my system permanently, eventually requiring me to remove and re-install Anaconda.

Sometimes it works and other times it works for a while and then breaks (and leaves the following errors at the bottom of this post). I have installed it at least 10 times in different conda environments over the past 4 years and about 4-5 times it ends up getting corrupted for some reason I have not been able to determine.

This current installation has been throwing the same error (below) for months now. Tonight (again) I tried to eradicate it, and after uninstalling it completely using the recommended command "jupyter labextension uninstall jupyterlab-code-snippets", the error still persists. The uninstall command finishes as though it succeeded. I even tried "pip uninstall jupyterlab-code-snippets", which says that it no longer exists.

It shows up after removing it and restarting the server a few times. I thought all traces of an extension are supposed to disappear after they are uninstalled?

Where do I remove this from the Jupyter "System Defaults" configuration file?

Found a solution in this post. You must remove the extra file leftover from a previous installation. The user-settings directory had a very old snippets config folder and file in it. Deleting that removed it from the Jupyter GUI.

See below from: jupyterlab/jupyterlab#4126

"there are probably stale settings files from a previous install (the editor settings JSON structure did change recently). You may find them in $HOME/.jupyter/lab/user-settings "

    {'lineWrap': True}

and when I look at the jupyterlab advanced settings editor, I see that it's set to True, but as you can see from the screenshot, that's what the settings came with, I didn't change anything, so what's this about?

Note that I previously installed alpha versions of j-lab, could this be a setting stored in non-conda folders that don't get wiped during a conda reinstall (which I do regularly for having a clean reproducible environment)?

j-lab version: 0.31.11-py36_1 conda-forge

Hi @michaelaye, I suspect you are right: there are probably stale settings files from a previous install (the editor settings JSON structure did change recently). You may find them in $HOME/.jupyter/lab/user-settings
