Intel Edison MRAA module not working

I recently downloaded the Intel XDK IOT version and used the LED pin 13 Blink sample.
I then uploaded the program onto the Edison, but it came up with a few errors; One of them being that it could not find the MRAA module. The sample code that came with it was:
main.js:

var mraa = new require("mraa"); //require mraa
console.log('MRAA Version: ' + mraa.getVersion()); //write the mraa version to the Intel XDK console

var myOnboardLed = new mraa.Gpio(13); //LED hooked up to digital pin 13 (or built in pin on Galileo Gen1 & Gen2)
myOnboardLed.dir(mraa.DIR_OUT); //set the gpio direction to output
var ledState = true; //Boolean to hold the state of Led

periodicActivity(); //call the periodicActivity function

function periodicActivity()
{
myOnboardLed.write(ledState?1:0); //if ledState is true then write a '1' (high) otherwise write a '0' (low)
ledState = !ledState; //invert the ledState
setTimeout(periodicActivity,1000); //call the indicated function after 1 second (1000 milliseconds)
}


package.JSON:

{
"name": "Onboard LED Blink App",
"description": "",
"version": "0.0.0",
"main": "main.js",
"engines": {
"node": ">=0.10.0"
},
"dependencies": {
}
}

Answer

echo "src mraa-upm http://iotdk.intel.com/repos/1.1/intelgalactic" > /etc/opkg/mraa-upm.conf opkg update opkg install libmraa0

the above answer has typos it should be "mraa" not "maa" and opkg not okpg
