Screenshots Just the prompt error when I open jupyterlab. And the code formatter extension doesn’t appear anywhere.

Additional context I had same issue with Jupyterlab 2.0.1 . I am using jupyter’s docker-stacks project. Adding to it a new docker layer which simply install extensions. I’ve tried installing with condas instead pip. I’ve tried reinstalling after container is created. And there is no version mismatch. Also, the “uninstalled” issue is not being a problem for me.

I meant do jupyter serverextension enable --py jupyterlab_code_formatter --sys-prefix in the Dockerfile

If you run that command by in a shell after you start the container and restart that change is not persisted, and also that is after jupyterlab starts up which is already too late.
