Not sure if bug or code problems

Hi there tried putting in the sample code:
// Load the node-omron-hvc-p2 and get a HvcP2 constructor object
const HvcP2 = require ('node-omron-hvc-p2');
// Create a HvcP2 object
const hvcp2 = new HvcP2();

// Connect to the HVC-P2
hvcp2.connect().then(() => {
// Send a command for detecting
return hvcp2.detect({
face: 1, // Enable face detection
age: 1, // Enable age estimation
gender: 1 // Enable gender Estimation
});
}).then((res) => {
// Show the result
console.log(JSON.stringify(res, null, ' '));
// Disconnect the HVC-P2
return hvcp2.disconnect();
}).then(() => {
console.log('Disconnected.');
}).catch((error) => {
console.error(error);
});

to see if it works, but the error <0x800a1391 - JavaScript runtime error: 'require' is not defined> so not sure what im doing wrong here, using VS 2017 and have installed all the required items except lwip, unless lwip is required, thanks!
