how can i edit ip address of raspberryPi in javascript?

Question

i want change ip address, subnet mask and gateway of Pi3 in node js.

i used module ' network-config ' and wrote and executed the code below.

var networkconfig = require('network-config');

networkconfig.configure('eth0',{

ip:         192.168.1.111,
netmask:    255.255.255.0,
gateway:    192.168.1.1,

},function(err){
    console.log(err);
});

but an error has occurred.

{Error: EACCES: permisiion denied, open '/etc/network/interfaces'
error:-13,
code:'EACCES',
syscall:'open',
path:'/etc/network/interfaces'}

I do not seem to have access, how do I get permission?

Or is there another way edit Pi's IP?
