I was wrong, I still have problems in running keplergl on OS X.

Have you tried installing Kepler.GL using a conda environment?

Hey there! I was able to produce this error on my conda environment. Apparently this is more of a Geopandas installation error. But good news is you can fix it easily! Follow these steps and it should fix your problem:

• First make sure you’re in the correct environment in Anaconda. (Creating a new environment for your project is suggested but it should work in base environment as well)

• Then open up the command prompt and install Geopandas using conda install geopandas command.

• After that run pip install defusedxml and python3 -m pip install --upgrade Pillow on the same command prompt to make sure all the dependencies work as expected.

• Finally install Kepler.Gl using pip install keplergl on the same conda environment.

Also I should mention that this method works perfectly for Jupyter Notebook and not Jupyter Lab. So I’d highly suggest you to use Kepler.GL on Jupyter Notebook because map won’t show up on Jupyter Lab and you need to troubleshoot and downgrade few dependencies to the correct version, install Kepler.GL extension, Node etc. for Kepler.GL to work.

This should fix all the errors. Hope this helps!
