by make build do you npm install?

I was unable to replicate. Can you tell us what OS you're doing this on, and if you ran any other commands?

@willemneal make build automatically calls npm install.

this OS is Ubuntu 18.04 LTS, I only ran the command "make clean & make"

Thanks. I don't have an Ubuntu machine to test this on; hopefully one of the other maintainers or community members will have an idea how to test this.
