Missing symbol?

还没有人认领这个 Issue。

Hey, I'm trying to make an electron app that searches for bluetooth devices as a test to see if I can get it to work, but I get this error when running my code.
```
dyld: lazy symbol binding failed: Symbol not found: __ZN2v811HandleScope12CreateHandleEPNS_8internal10HeapObjectEPNS1_6ObjectE
Referenced from: /Volumes/HaydenDrive/Code/Personal/Applications/Bluetooth/node_modules/node-bluetooth/build/Release/BluetoothSerialPort.node
Expected in: flat namespace
```

I'm not entirely sure what to do, as I've only just built the package using NPM.
I'm running macOS 10.14.03, using the v4.0 of electron.

Here's my code in the js file linked to my index.html:
```js
const bl = require('node-bluetooth');
const device = new bl.DeviceINQ();
device
.on('finished', console.log.bind(console, 'finished'))
.on('found', function found(address, name){
let row = deviceTable.insertRow()
let devName = row.insertCell(0);
let devMAC = row.insertCell(1);
devName.innerHTML = name;
devMAC.innerHTML = address;
}).scan();
```

从与 index.html 关联的 JavaScript 中的 require('node-bluetooth') 入口点，以及错误中报告的已构建文件 node_modules/node-bluetooth/build/Release/BluetoothSerialPort.node 开始。使用 Electron v4 在 macOS 10.14.03 上重现该故障，然后检查 native addon 的构建和加载方式。当应用能够 require 该 package 并在没有 missing-symbol 错误的情况下完成 Bluetooth 扫描时，即表示完成。
