Is this in development or a built app?

Looks like a warning to me, not an error. So it shouldn’t break anything.

Most likely fix is to use meteor npm rebuild to rebuild the c++ extensions. Or nuke the node_modules directory and meteor npm install again

this is for development, ok thank you, i will try as you suggested.
