@DavidBrochart actually what you are describing is the expected behavior. Lab extension fetch the js assets from npm.

To install the lab extension from source, you need to specify a directory instead.

Yes, we’ve combined the js packages and published the result. Now it is just jupyter labextension install jupyter-leaflet.

In the next revision, we may even be able to dispense with even that - and install the jlab plugin automatically when you install the python package.
