Getting Error EBUSY: resource busy or locked

var onoff = require('onoff');
var Gpio = onoff.Gpio,
    led = new Gpio(4, 'out'),
    interval;
interval = setInterval(function () {
    var value = (led.readSync() + 1) % 2;
    led.write(value, function () {
        console.log("Changed LED state to: " + value);
    });
}, 2000);
process.on('SIGINT', function () {
    clearInterval(interval);
    led.writeSync(0);
    led.unexport();
    console.log('Bye, bye!');
    process.exit();
});

There are many answers on GitHub regarding this issue.

• Some says npm cache clean this command executing on terminal solved the problem.

• Others recommend to delete the entire directory your app is the folder in and re-install the packages and then try running the program.

• Some also says that It is caused by the anti-malware software and recommend to disable it while running the program.

If it doesn't solve the issue, just change the GPIO pin to let's say 23 in coding and don't forget to physically replace LED from 4 to 23 too.

This problem can occur when you try to write to a file that is open in an editor
