JavaScript heap out of memory

[lbois]

I'm trying to convert a KML file that is 107 mb to geojson using the command line. It's a geospatial dataset from DATA.GOV about airports in the US. I installed togeojson with npm install -g @mapbox/togeojson . I'm on Mac OS High Sierra npm 5.7.1 node v8.9.4. Does anyone know how to fix the following error I'm getting Or is the KML file too big?

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory
1: node::Abort() [/usr/local/bin/node]
2: node::FatalException(v8::Isolate*, v8::Localv8::Value, v8::Localv8::Message) [/usr/local/bin/node]

7: 0x4994fd364e7
8: 0x4994fd2301f
Abort trap: 6

And the output file gives the errors too

I have a file that is 475MB that I need to convert... Hope you guys can get this updated. Much appreciated all you are doing, but it looks like PHP has Node.js whipped in dealing with KML files for now.

You can allocate more ram with the following command:

NODE_OPTIONS=--max_old_space_size=4096 togeojson [your command]

Did this work? I also have the same issue.
