This is an issue with the installation of netCDF4 (which is an indirect dependency via arviz), rather than exoplanet directly. I've also previously found that the pip binary wheel for mac is broken and fixed it by installing netCDF4 with conda (conda install -c conda-forge netcdf4), but there might be other ways to get an installation that works!
