我很難嘗試使用groovepi和pi 3來查找nodejs示例。我想要做一個簡單的hello世界上，我發現與愛迪生愛迪生groovepi樣品，但顯然沒有奏效。無法打開moddep> file'/lib/modules/4.4.26-v7+/modules.dep.bin
做了一點研究，我找到了johny五個庫，但它只適用於arduino，但它們應該有其他板子的插件，比如覆盆子，所以安裝rasp-io，johnny五並試圖運行這個示例
var raspi = require('raspi-io');
var five = require('johnny-five');
var board = new five.Board({
io: new raspi()
});
board.on('ready', function() {
var lcd = new five.LCD({
controller: "JHD1313M1"
});
lcd.bgColor(r, g, b).cursor(0, 0).print(f);
});
我得到這個錯誤：
