Get Default Gateway macOS

[Lucaslah]

On macOS the get default gateway script dose not work.

network.get_gateway_ip(function(err, ip) {
  console.log(err || ip); // err may be 'No active network interface found.'
})

This is because the command ipconfig getoption en0 router dose not work on macOS

Here is the error:

Error: Command failed: ipconfig getoption en0 router
