node@8.12.0 (latest 8.x), which is what Travis is using to build and test this repository, works fine, but previous versions do not.

This is particularly inconvenient if working with environments where node version is locked, such as AWS Lambda.

Turns out xcode-select -r was all I needed to make this work correctly on macOS High Sierra 10.13.6.

Still cannot explain why 8.12 was working properly - but running above command solved the issue for me.

Closing.
