Raspberry Pi NodeJS Error

I have a raspberry pi 2 Model B V1.1 and I have followed the instructions online and every time I press a button on my phone on the blynk app it comes up with a error. I have no java knowledge so I don’t know what it means. This is the error that comes up:
var pin = new mraa.Gpio(parseInt(values[1]));

Error: Illegal arguments for construction of _exports_Gpio

and I don’t know what it means
Can someone help me because I have been doing this for about 6 hours.
