我很难尝试使用groovepi和pi 3来查找nodejs示例。我想要做一个简单的hello世界上，我发现与爱迪生爱迪生groovepi样品，但显然没有奏效。无法打开moddep> file'/lib/modules/4.4.26-v7+/modules.dep.bin
做了一点研究，我找到了johny五个库，但它只适用于arduino，但它们应该有其他板子的插件，比如覆盆子，所以安装rasp-io，johnny五并试图运行这个示例
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);
});
我得到这个错误：
