dbus.go::: undefined: dbus.ConnOption

I'm trying a simple test with go-systemd. Nothing fancy. But the build failed with the following error:

# github.com/coreos/go-systemd/dbus
/root/go/pkg/mod/github.com/coreos/go-systemd@v0.0.0-20191104093116-d3cd4ed1dbcf/dbus/dbus.go:146:47: undefined: dbus.ConnOption
/root/go/pkg/mod/github.com/coreos/go-systemd@v0.0.0-20191104093116-d3cd4ed1dbcf/dbus/dbus.go:204:53: undefined: dbus.ConnOption
/root/go/pkg/mod/github.com/coreos/go-systemd@v0.0.0-20191104093116-d3cd4ed1dbcf/dbus/dbus.go:224:58: undefined: dbus.ConnOption

The source code it's just a test:

package main

import (
    "fmt"

    "github.com/coreos/go-systemd/dbus"
)

func main() {

    systemdConnection, _ := dbus.NewSystemdConnection()

    listOfUnits, _ := systemdConnection.ListUnits()

    for _, unit := range listOfUnits {
        fmt.Println(unit.Name)
    }

    systemdConnection.Close()
}

All I want is to perform basic action in my golang code:

1. Get the list of units (running and stopped);
2. Get status of a running unit;
3. Start/Stop a specific unit;

Does anybody have any idea about what is going on?
