About linux : osGetenvGOPATH-not-retrieving-value-in-Ubuntu

I am noob in Golang, also I have browsed all the answers relative to this issue in stackoverflow but I haven’t found anthing to answer my problem.

If I enter the command in console -> get env I got this:

GO111MODULE=""
GOARCH="amd64"
GOBIN=""
GOCACHE="/home/adi/.cache/go-build"
GOENV="/home/adi/.config/go/env"
GOEXE=""
GOEXPERIMENT=""

GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOINSECURE=""
GOMODCACHE="/home/adi/go/pkg/mod"
GONOPROXY=""

GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build1114163046=/tmp/go-build -gno-record-gcc-switches"

but if I am trying to output

func main() {
    // router := gin.Default()
    // RegisterBlocklyAutomationEndpoint(router)

    fmt.Println(os.Getenv("GOPATH"))

}

I get an empty string. I really need to get the value in order to use it in path formation for some static resources.

Thanks!
