Installation issue from JupyterLab extension manager

The front page directions do work after upgrading jupyter lab to the latest.

jupyter labextension install @jupyterlab/git
pip install jupyterlab-git
jupyter serverextension enable --py jupyterlab_git

I originally installed the extension with via the UI (ext manager) but couldn’t get it to work.

Running the steps above from the command line solved the issue!

Note for completeness: just because we are changing the plugin distribution and build system in Jupyterlab does not entail that we will stop having a UI frontend for discovering and managing extensions. It will close this issue though (assuming that the current plan ends up working).

A real solution to this issue would require significant enhancements to the labextension GUI in core. These likely won’t happen, since the current plan is to jettison the labextension manager from core entirely. Instead we’ll bundle each plugin’s lab- and/or serverextension together in a single Python package, and then let pip/conda sort out everything else. So in that sense, this issue is a won’t fix.

On the bright side, after the work done in #415 and #458, an end user need only now install the pip package and then (re)build the app:

pip install jupyterlab-git
jupyter lab build

in order to get a completely functional instance of the @jupyterlab/git plugin running. So that at least addresses the concern of an end-user needing to grasp the lab/serverextension distinction
