I've tried to debug my hello world program in go and cannot get debugging to work.

I've installed via homebrew and the google website. I've tried various online config, installed delve and breakpoints just won't stick.

Paths

export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOPATH/bin:/usr/local/go/bin
