Can't get this extension working on my jupyter lab environment

I’m using python 3.7.6 And below is my jupyter enviroment (obtained with conda list jupyter)

# Name                    Version                   Build  Channel
jupyter                   1.0.0                      py_2    conda-forge
jupyter_client            6.1.3                      py_0    conda-forge
jupyter_console           6.1.0                      py_1    conda-forge
jupyter_core              4.6.3            py37hc8dfbb8_1    conda-forge
jupyterlab                2.1.2                      py_0    conda-forge
jupyterlab_server         1.1.3                      py_0    conda-forge

I have tried jupyter lab clean and then jupyter lab build, but still can’t get it working. I have successfully used the vim extension on jupyterlab 1.X. I also noticed that there’s a system default shortcut ii for interrupting the kernel. However, disabling it won’t help either.

What’s other possible causes ? Thank you very much.

I was not able to make this extension work with jupyterlab 3.0.0 and after installing the extension using pip install jupyterlab_vim. I checked that the extension was activated (“enabled OK”) using jupyter labextension list. I tried the above suggested fix, but it did not help. I then uninstalled the extension again using pip, downgraded to jupyterlab 2.2.9 and re-installed the package using jupyter labextension install @axlair/jupyterlab_vim. Now it works.

One thing I found confusing: While the extension was not working I was unsure if there was a problem with the installation or if I just didn’t know how to enter vim command mode. It would be great if the readme could have something about what it’s supposed to look like when it’s working.

I was having trouble too with Jupyter 2.1.5. To check my extensions, I did the following:

$ jupyter labextension list
JupyterLab v2.1.5
Known labextensions:
   app dir: /Users/dcheng/miniconda/share/jupyter/lab
        @axlair/jupyterlab_vim v0.12.4  enabled  OK
        @jupyterlab/toc v4.0.0  enabled  OK
        jupyterlab-plotly v4.8.2  enabled  OK

Uninstalled core extensions:
    @axlair/jupyterlab_vim

In order to fix my problem I had to delete the file mentioned in #12. In my case it was rm ~/miniconda3/share/jupyter/lab/settings/*.json

After that I did a jupyter lab clean; jupyter lab build, everything worked.

Hope that helps.
