Install to current version of jupyterlab (2.1.1) not working

[jerri]

I have a small script to install jupyter and jupyterlab into a virtual environment. After installing jupyterlab, I try to install jupytherlab-vim. This worked in the past, but right now I get the following error:

> jupyter labextension install jupyterlab_vim
An error occured.
ValueError: The extension "jupyterlab_vim" does not yet support the current version of JupyterLab.


Conflicting Dependencies:
JupyterLab              Extension      Package

See the log file for details:  /tmp/jupyterlab-debug-o2s9wxtj.log

I install jupyter and jupyterlab via pip inside the virtual environment. Am I doing something wrong? jupyterlab-vim is supposed to support 2.1.1, no?

Sounds like there is active work to support JupyterLab 2.x. It's a fairly new release, so extensions are still working to catch up.

According to #115, until changes are merged, a temporary fix is to install from the forked repository with jupyter labextension install @axlair/jupyterlab_vim

Just for an update. I tested the install of jupyterlab_vim again with current version of jupiter. And it still fails. The only way to install it is via the way mentioned by jmerizia. Therefore it might make sense to document this properly in the READMEs?
