Fix for JupyterLab 4.3.4. Edit the file:

$HOME/.jupyter/lab/user-settings/@jupyterlab/notebook-extension/tracker.jupyterlab-settings

and change

    "codeCellConfig": { 
        "lineNumbers": false, 
    },

to true. Then restart JupyterLab.

I'm new at this so don't flame me. But Frank said from View -> Show Line Numbers. I did this from main JupyterLab window. I'm using version 3.5.0.

In your Jupyter Lab, click the chain, View -> Line numbers. This solution is from this GitHub issue.

you can turn this on by default by going into Settings --> Advanced Settings Editor:

As you can see from the screenshot, you can edit other features as well and easily set them back to default by deleting your 'User Overrides'

Go to Settings > Advanced configuration and add:

{
    "codeCellConfig": {
        "lineNumbers": true
    }
}

Late reply, but it'll still help others!

For Windows users, just hit Shift + L

You can go to View -> Show Line Numbers:

which will display line numbers in the notebook:
