Cannot build Grafana from source with build.go

Grafana Plugin Development
1

I’m using go version go1.11.1 darwin/amd64 on macOS 10.14. I have grafana checked out to $GOPATH/src/github.com/grafana/grafana on latest master (4a77a62949eaef72899b036b981b03a4266dc426 as of writing this).

When I run go run build.go setup, there are a lot of errors like:

It looks like more Go dependencies need to be fetched, but running build.go does not do this?

Did you do go get github.com/grafana/grafana first or did you use git to clone the grafana repo - in that case remove checked out code/repo locally and then do a go get github.com/grafana/grafana followed by `go run build.go setup.

Yep that was it, I had originally just git cloned the repo into my $GOPATH, redoing with go get fixed it - thanks a lot!
