Johnny-Five无法连接到Arduino

Question

Windows 10、Arduino Micro。我最初使用的是标准的"Blink.js“教程，但是Johnny-Five一直连接到错误的串行端口。我硬编码了我的COM端口(在本例中是端口8 )，并通过了最初的错误，但是一个新的错误阻止了我。我的输出如下所示：

C:\Users\...\folder>node Blink.js
1536475383667 Connected COM 8
1536475383673 Error Opening COM 8: File not found
(node:12700) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Uncaught, unspecified "error" event. ([object Object])
1536475393671 Device or Firmware Error A timeout occurred while connecting to the Board.

    Please check that you've properly flashed the board with the correct firmware.
    See: https://github.com/rwaldron/johnny-five/wiki/Getting-Started#trouble-shooting

If connecting to a Leonardo or Leonardo clone, press the 'Reset' button on the board, wait approximately 11 seconds for complete reset, then run your program again.
events.js:165
    throw err;
    ^

我已经做了他们推荐的所有明显的事情:重新刷新固件，刻录引导加载程序，重新安装节点和npm，一步一步地完成了Arduino的安装说明，尽管我不得不通过图形用户界面而不是命令行来推送standardFirmataPlus.ino，因为Windows本身并不包含用于Arduino的命令行工具。我的代码，如果有什么不同的话，看起来像这样：

var five = require("johnny-five"),
    board, led;

board = new five.Board({port: "COM 8"});

board.on("ready", function() {
  console.log('ready');
  led = new five.Led(8);    //This would be port 13 on most, but the Micro doesn't have that port
  led.strobe(100);
});

多年来，我一直在努力从使用Johnny-Five的Arduino中获得任何反应，任何帮助都将不胜感激。

事实证明，这个问题是交叉兼容性的问题。我使用Git在计算机之间同步文件和项目，一台计算机是Mac，另一台是Windows。与许多其他JavaScript包不同，serialport是一个特定于平台的包。所以，学习使用gitignore吧。

希望这对其他人有帮助。
