I'm trying to get all the devices connected on the network but I'm having this error.

Trace: Error: Error: spawn nmap ENOENT

Main.js

var opts = {
    range : [
        "***.***.*.0",
        "***.***.*.225",
    ],
}   

nmap.scan(opts, function(err, report) {
   
    for (let item in report) {
      console.log(JSON.stringify(report[item]));
    }
});

If you haven't set the nmap binary path, you need to set the environment variable in windows.
