button can't work

[sxj123]

this is my button.js:
var Cylon = require('cylon');

Cylon.robot({
connections: {
pcduino: { adaptor: 'pcduino }
},

devices: {
button: { driver: 'button', pin: 2 }
},

work: function(my) {
my.button.on('push', function() {
console.log("Button pushed!");
});
}
}).start();
$node button.js
TypeError:Cylon.IO.Utils.every is not a function
Why? Is the pin.js file wrong?Looking forward to your reply.

Hi, sxj123

instead of using driver button, you can use driver led, like the following
devices: {
led: { driver: 'led', pin: 2 }
},

as instead of using event push, you can inspect pin and use the following
digitalWrite
digitalRead
setHigh
setLow

if there is still problem, please give feedback :)

Hi,alex:
this is the led blink code:
`'use strict';
var Cylon = require("cylon");

Cylon.robot({
connections: {
pcduino: { adaptor: 'pcduino' }
},

devices: {
	led: { driver: 'led', pin: 10 }
},

work: function(my) {
	every((1).second(), my.led.toggle);
}	

}).start();
` and it works.
button and led both call for digital interface, the led blink can work, why button can't?
In order to let the terminal show "button pushed" when the button is pushed, how to write the code in the work part? I don't know how to use the function code to implement this function. Could you please help?
Looking forward to your reply! Thanks so much!
