npm - SerialPortIO Electron

Question

我正在尝试运行一个简单的 Electron 应用程序来从端口 COM4 读取和写入值，我已经下载并正确安装了 node.js 和 serialport io，这就是我这样做的方式:

$ git clone https://github.com/electron/electron-quick-start
# Go into the repository
$ cd electron-quick-start
# Install the dependencies and run
$ npm install && npm start

一旦完成。安装串口库。

$ npm install --save serialport 
$ npm install --save-dev electron-rebuild  

重建 Electron

$ ./node_modules/.bin/electron-rebuild
$ npm rebuild

这是我的 index.html

        var SerialPort = require('serialport');
        const Readline = serialPort.parsers.Readline;

        //initialize serialport with 115200 baudrate.
        var sp = new serialPort('COM4', {
            baudRate: 115200,
        });

        function writeonSer(data){
            //Write the data to serial port.
            sp.write( data, function(err) {
                if (err) {
                    return console.log('Error on write: ', err.message);
                }
                console.log('message written');
            });

        }
    </script>
    <script>
        // You can also require other files to run in this process
        require('./renderer.js')
    </script>

最后我收到了这个错误

Uncaught Error: The module '\\?\C:\Users\atorres\Desktop\SerialPort\electron-quick-start\node_modules\@serialport\bindings\build\Release\bindings.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 64. This version of Node.js requires
NODE_MODULE_VERSION 73. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

请帮忙!谢谢。

通过安装 Visual Studio C++ 开发包，我设法让 github.com/serialport/electron-serialport 在 Windows 环境中工作。我遇到了与您之前遇到的类似错误。具体来说，它需要 MSVS 构建工具。 https://visualstudio.microsoft.com/downloads/工具可以在这里 :)

我还尝试使用 NVM-Windows 并运行 SerialPort/Bindings 目录文件中指定的模块版本。这实际上没有用，所以也许错误报告不正确？无论如何，希望这会有所帮助。
