Failed to load the jupyterlab-git server extension

Description

I get the below warning every time I load jupyterlab and the git extension doesn’t load but I can see that it’s installed and there’s a section for the git extension on the advanced settings menu

After doing running the suggested pip install --upgrade jupyterlab-git

I get the following output and it looks like I have every package I need

Gotcha! thanks for the help, it’s a handy little extension. Not as good as the git vscode ext with inline code git info but I’m glad to have it!

[krassowski]

That’s good! After restarting JupyterLab, does the extension work too?
