geojson convert to geobuf failed

[hoogw]

I use windows. in command line window, I type:

node \jh\other_map_geojson\node_modules\geobuf\bin\json2geobuf city_zoning.geojson > city_zoning.pbf

I got a 0 size pbf file. the error is:

What Node version are you using? Can you try Node v4+?

[hoogw]

C:\jh\other_map_geojson>node -v v0.10.36

Good catch, my node version is too old. now I am update it to

C:\jh\other_map_geojson>node -v v6.9.1

I try: node \jh\other_map_geojson\node_modules\geobuf\bin\json2geobuf \jh\other_map_geojson\Raw_geojson\city_parcels.geojson > \jh\other_map_geojson\Raw_geojson\city_parcels.pbf

It works perfect!!!

Thank you so much, I stuck 8 hours didn't figure out it is version problem.
