找不到模塊“約翰尼五號”？

Question

我對此很陌生，如果答案很明顯，那么抱歉。我正在嘗試對 Arduino Uno 板進行編程，以點亮面包板上的 LED，它通過 node.js 連接到 Raspberry Pi 3b+（使用 rpi 作為桌面）。 我安裝了 node.js 版本 14.9.0 並通過它 johnny-5，然后我安裝了 Arduino IDE 並使用它將 StandardFirmata 下載到 Arduino 板上。 我通過 nano 編寫了一個簡單的程序，然后使用node led.js運行它。 然后我收到此錯誤消息：

internal/modules/cjs/loader.js:895
  throw err;
  ^

Error: Cannot find module 'johnny_five'

  requireStack: [ '/home/pi/led.js' ]
}

知道為什么嗎？ 幫助將不勝感激。 謝謝！

之后的輸出：

你確實需要（“johnny_five”）。 你應該做 require("johnny-5")
