Working on an Electron JS app for linux.
Followed the installation process given in about page, getting following errors while installing the package unable to proceed further.

OS - Ubuntu 16.04
Node - 12.8.1
NPM - 6.10.2
Electron JS - 7.0.1
Node-gyp - 5.0.3

まず、Node 12.8.1、node-gyp 5.0.3、Electron 7.0.1、Ubuntu 16.04 を使用して npm install を再現し、その後 src/linux/BluetoothSerialPort.cc の InitAll と NODE_MODULE エントリポイントの周辺を調査します。報告されている C++ ビルドエラーなしで node-bluetooth パッケージのインストールに成功すれば完了です。
