Install it on jupyterhub

[amasanelli]

Hello I'm running jupyterhub on a gcp VM. I followed these steps https://tljh.jupyter.org/en/latest/install/google.html to install jupyterhub

Now I'm trying to install jupyterlab-git but I can't successfully complete this task.

After I run the command and reload the browser an alert appear saying:

Failed to load the jupyterlab-git server extension
Git server extension is unavailable. Please ensure you have installed the JupyterLab Git server extension by running: pip install --upgrade jupyterlab-git. To confirm that the server extension is installed, run: jupyter server extension list.

Hey @amasanelli

• how did you install the extension?
• could you please report the output of jupyter serverextension list?

[amasanelli]

Hi, I run the command sudo pip install --upgrade jupyterlab-git on
jupyterlab terminal

The output of jupyter serverextension list is on the body of my question

Thanks

There are two commands jupyter serverextension list and jupyter server extension list (note that one has a whitespace between server and extension) - the former is used by the classical notebook (and JupyterHub) when the second is used by jupyter-server and JupyterLab v3 (if not executed in JupyterHub context). In your first post, the terminal copy is showing jupyter server extension list. Hence my question to get the output of the other one jupyter serverextension list. But it may be safer to run again both commands to be sure.

Oh sorry about that.

Here is the output of both:

I found the solution!

I installed it running sudo pip install --upgrade jupyterlab-git on the jupyterlab terminal and then I restarted the server using the jupyterhub control panel.

Now it's working!

Thanks

Great to hear

[fcollonval]

Oh sorry about that.

Don't worry those small diff are hard to catch 😉
