Failed to load jupyterlab-git server extension

Question

I am trying to install git extension in jupyterlab but I get error as below. All server extensions are enabled but it doesn't load.

(base) [root@user01 opt]# jupyter serverextension list
config dir: /opt/anaconda3/etc/jupyter
    jupyterlab  enabled
    - Validating...
      jupyterlab 2.2.6 OK
    jupyterlab_git  enabled
    - Validating...
      jupyterlab_git 0.23.3 OK
    nbdime  enabled
    - Validating...
      nbdime 2.1.0 OK

As suggested in another page I have installed jupyter_nbextensions_configurator but still that didn't help. I am running jupyterlab from jupyterhub on linux machine.

Is the output of the command exactly equal to `git version 2.23.3` or does it differ? — krassowski, Jan 27 '21 at 14:21
uninstalled everything and redone and the extension is working fine now but `Git Clone` button is greyed out in File explorer. Any idea on this @krassowski ? — mockash, Jan 27 '21 at 15:08
Maybe https://github.com/jupyterlab/jupyterlab-git/issues/809? It seems to have been fixed in master, so should be work fine once the new version for JupyterLab 3.0 gets released in the coming days. — krassowski, Jan 27 '21 at 15:14
I am surprised that issue didn't show up in google for me while searching. Thanks for that. — mockash, Jan 27 '21 at 16:05

This is a known bug introduced in jupyterlab-git 0.22.2. The comments in the GitHub issue mention that refreshing browser may help but I have not tried it. This issue was fixed in the new version for JupyterLab 3.0- you can install it with:

pip install jupyterlab==3
pip install jupyterlab-git==0.30

If you cannot yet update to JupyterLab 3.x, you can downgrade to 0.22.1 which is not affected:

pip install jupyterlab-git==0.22.1

I had a similar issue and solved it with updating git on my Windows machine, and then updating jupyterlab-git. – Life is Good May 06 '22 at 15:14

I don’t know if it’s an option for many people, but I was having this issue, and it helped me to restart the Jupyter server (to restart the OS).

That did the trick for me. I installed the extension, ran the rebuild command and the error being thrown read "Failed to load the jupyterlab-git server extension..." together with instructions to ensure it's installed and check that it's enabled, which it was. I was able to fix it by restarting the server on which the jupyter lab was hosted. – Marceli Wac Mar 30 '23 at 12:54

The link above says that some people are getting this error because a new version of the extension has not been released for JL3.

So install the older version.

Add below git binary file locations to PATH environment variable:

%PROGRAMFILES%\Git\mingw64\libexec\git-core

%PROGRAMFILES%\Git\usr\bin

and then restart the Jupyter session.
