 am new to johnny-five.js framework (javascript-iot) I would like to do some "hello world" in johnny-five by blinking the onboard led at the arduino board and according to some tutorials the board is at default pin 13 and this is the error..

/home/botkiller/javascript/samplej5/node_modules/bindings/bindings.js:96 throw err ^

Error: Could not locate the bindings file. Tried: → /home/botkiller/javascript/samplej5/node_modules/serialport/build/serialport.node → /home/botkiller/javascript/samplej5/node_modules/serialport/build/Debug/serialport.node → /home/botkiller/javascript/samplej5/node_modules/serialport/build/Release/serialport.node → /home/botkiller/javascript/samplej5/node_modules/serialport/out/Debug/serialport.node → /home/botkiller/javascript/samplej5/node_modules/serialport/Debug/serialport.node → /home/botkiller/javascript/samplej5/node_modules/serialport/out/Release/serialport.node → /home/botkiller/javascript/samplej5/node_modules/serialport/Release/serialport.node → /home/botkiller/javascript/samplej5/node_modules/serialport/build/default/serialport.node → /home/botkiller/javascript/samplej5/node_modules/serialport/compiled/10.0.0/linux/x64/serialport.node at bindings (/home/botkiller/javascript/samplej5/node_modules/bindings/bindings.js:93:9) at Object.

(/home/botkiller/javascript/samplej5/node_modules/serialport/lib/bindings/auto-detect.js:16:22)

I uploaded the standard firmata at my board and install all the dependencies to use the johnny-five to arduino...

Here is my code:

const j5 = require('johnny-five');
const board = new j5.Board();

board.on("ready", function(){

    this.pinMode(13, 1);
    this.loop(1000, function (){
        this.digitalWrite(13, 1);
    });

});

You can try downloading the npm and node.js through linuxbrew but install them not in root. Which it is the cause of the error, that the computer can't communicate the device (Arduino) because you have to access the root library of your computer..
