Building from source seems to thrown an exception

Am trying to build K6 from source. Am trying to follow the steps listed in README. However when I execute
go get
it ends up with an exception
build cannot load hash/maphash: malformed module path "hash/maphash": missing dot in first path element.
Am unsure as to what is missing in my environment. Am on go version go1.13 darwin/amd64



this looks like some incompatibility with Go 1.13. I can reproduce it with that version, but the command runs fine with 1.14 and 1.15. Can you try updating your Go version?
