jupyterlab-git: Installation instructions have you installing mismatched versions

Description

pip install --upgrade jupyterlab jupyterlab-git installs backend version 0.23.3

jupyter labextension install @jupyterlab/git installs frontend version 0.30.0b1

When you install the two extensions this way and then open JupyterLab you get a message telling you that the two versions are not the same and to run pip install --upgrade jupyterlab-git to fix it:

But the pip install --upgrade jupyterlab-git command also installs the 0.23.3 version. So this isn’t a viable solution. The only way for me to get matching versions was to run pip install jupyterlab-git==0.30.0b1 (and I’m assuming we regular users don’t want to be running beta versions, right? I couldn’t figure out how to install the 0.23.3 frontend version, so I’m stuck using both beta versions for now).

Reproduce

After running pip install --upgrade jupyterlab jupyterlab-git you can then run pip list to check the version of the backend version (and in this case see that it is version 0.23.3).

After running jupyter labextension install @jupyterlab/git you can then run jupyter labextension list to check the frontend version (and in this case see that it is version 0.30.0b1).

Expected behavior

When I ran those initial commands to install the extensions I expected both versions to match and to not have to troubleshoot why my versions weren’t matching.

Context

Not sure additional context is needed, but happy to provide if so!

Ok the error is due to the jupyterlab version. No release has been done for JupyterLab 3 (see #779).

So you should either install the beta version for JLab 3 or stick with JLab2 for now.

To install the beta version, you need to execute:

pip install --pre jupyterlab-git==0.30.0b1

And nothing else, JLab3 introduces a way to load directly the extension in the frontend.

For now, using pip (there should not be any trouble with conda), you can either install the stable version on JupyterLab 2 (requires nodejs):

pip install jupyterlab~=2.2.9 jupyterlab-git
jupyter lab build

To check the version:

jupyter serverextension list
jupyter labextension list

Or try the beta version on JupyterLab 3:

pip install jupyterlab~=3.0
pip install --pre jupyterlab-git==0.30.0b1

To check the version:

jupyter server extension list
jupyter labextension list

There is a space between server and extension for JupyterLab 3 as the server changed.

If you mixed up version, best is to remove the environment you created. If this is not possible, run jupyter lab clean --all, remove the packages and install them again.

Glad you successfully installed it.

I installed it with jupyter labextension install, then I use pip to install the server side package.

With JupyterLab 3, you only need to install the python package via pip. JupyterLab will load the js files directly without the need of rebuilding like for JupyterLab 2 or earlier.

Your error is coming from @datalayer-jupyter/jupyterlab-git v0.30.0 enabled OK

There is a conflict with that extension - you should remove or disable it.

By doing so I have this error JupyterLab - Google Chrome_18

Even if it seems installed:

(I am on CentOS 8 jupyter lab 3.0.5 served by jupyter hub)
