There's a summary of the relevant changes in jupyterlab here:

https://jupyterlab.readthedocs.io/en/stable/developer/extension_migration.html

Here is some extra detail

Before the plugin turns compatible with Jupyter Lab 2.0, creating a standalone environment with jupyterlab=1.2.7 works for me. The setup script is below:

    conda create -n Jlab_V1 python # Create a new env with python
    conda activate Jlab_V1
    # Install necessary pieces
    conda install -y -c conda-forge jupyterlab=1.2.7 nodejs yarn
    # Collect all extension pieces
    jupyter labextension install --no-build jupyterlab_vim @jupyterlab/toc jupyterlab-spreadsheet
    # Name the tabs appropriately
    jupyter lab build --name="JLab_V1 with Vim"
    # Lastly, we verify that the plugins are installed (jupyterlab-vim among them):
    jupyter labextension list

On this conda-jupyterlab page, version 1.2.7 is the latest one before V2.0.

Hello...

I'm facing the same need. ☺️ I've been using vi(1) since when I was stuck in datacenters with only vt100 terminals and Sun Solaris CLI prompts.
So it's nearly impossible to work without vi(1).

user$ jupyter labextension install jupyterlab_vim

UPDATE :

I found and successfully implemented the solution to this issue here:

+1 , I cant use these notebooks without vim anymore it seems. Just way too uncomfortable without it :)

This version should work: https://github.com/axelfahy/jupyterlab-vim

You also don't need to manually install extensions. Try this: 1) get the latest Jupyter Lab; 2) using UI, install vim extension (see attached image).

@KwatME Thanks for the link!

Excited for this to get merged!

"The extension "jupyterlab_vim" does not yet support the current version of JupyterLab." Really?

"The extension "jupyterlab_vim" does not yet support the current version of JupyterLab." Really?

It seems this repository hasn't been committed to since July 2019 so I'm just going to switch to https://github.com/axelfahy/jupyterlab-vim. Thanks @KwatME
