Unable to load layers #1061

Closed moovida closed 2 years ago

moovida commented 2 years ago

Hi, I am having issues adding even simple layers to the Map object in jupyterlab.

I ended up trying the simple marker example from the docs, but that also fails. I am not getting any error, just the broser console shows me something is failing with addLayer:

Any idea what is going wrong? Thank you

Thanks for opening an issue.

Which ipyleaflet version do you use?

Also can you show us the output of jupyter labextension list?

moovida commented 2 years ago

I am using ipyleaflet 0.17.1

The extensions list shows me:

JupyterLab v3.4.6
~/.local/share/jupyter/labextensions
        jupyterlab_pygments v0.2.2 enabled OK (python, jupyterlab_pygments)
        jupyter-leaflet v0.17.1 enabled OK
        @jupyter-widgets/jupyterlab-manager v5.0.3 enabled OK (python, jupyterlab_widgets)

Other labextensions (built into JupyterLab)
   app dir: ~/.local/share/jupyter/lab
        js v0.1.0 enabled OK

Thanks for the fast reply.

Do you know what this could be?

Other labextensions (built into JupyterLab)
   app dir: ~/.local/share/jupyter/lab
        js v0.1.0 enabled OK
moovida commented 2 years ago

Yes, (or better, I know why it is there), when I was looking for solutions I found a user saying that after installing that js extension, it worked. I had previously installed the other extensions though.

martinRenou commented 2 years ago

There should be no need for this.

I'd suggest removing entirely the ~/.local/share/jupyter/labextensions and ~/.local/share/jupyter/lab folders, and try again a clean installation with just pip install ipyleaflet.

moovida commented 2 years ago

ok, will try that. Should I install the jupyter-leaflet extension, or is that no longer necessary?

martinRenou commented 2 years ago

Just pip install ipyleaflet is enough, there should be no need to run jupyter labextension install * commands anymore.

moovida commented 2 years ago

And you were right. Reinstalled everything clean and it works perfectly. Not sure when I messed up things now. Thanks a ton.

martinRenou commented 2 years ago

It's really unclear to me as well, the error message you were getting is nothing that I recognize!

Happy that you could get it to work :)
