升级后Golang Bin无法运行

I've upgrade the Golang version for 10.3 to 11 before the upgrade I've some bin which I build for MAC like following in make file

GOB=$(GOCMD) build

`CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 $(GOB) -o build/$(BINARY_NAME) -v`

the bin is copied to go/bin

/Users/z0467676/go/bin

The binary is a CLI and before when I run it I did something like this for example

fst -h and it works

Now when I do it I got error

Unknown command 'fst'

Any idea what could be wrong and how to fix it ?

I see the bin in the go/bin/fst
