Help me Grafana install

I am using MacOS version 10.12.3 I follow the guide building_from_source but meet some error.

liujjcdl ~/go> go get
can’t load package: package no buildable Go source files in /Users/liujjcdl/go/src/

Any suggestion how to make it work? Thanks very much.

That is just a warning, continue build guide

Thanks very much for the quick rely, I will try it.
