我一直试图通过node-red-node-arduino按照Node-Red自己的指南（https://nodered.org/docs/hardware/arduino）安装Node-Red中的arduino节点无济于事 . 该节点在"Manage Palletes"选项卡中标记为已安装，但它识别它 . 我安装了包arduino-firmata和node-red-node-serialport，以及所有包本地（〜/ .node-red / node_modules）和全局（通过npm中的-g选项），但情况保持不变 .
cd ~/.node-red
npm install node-red-node-arduino
npm install arduino-firmata
npm install node-red-node-serialport
sudo npm -g install node-red-node-arduino
sudo npm -g install arduino-firmata
sudo npm -g install node-red-node-serialport
但是，至少在本地安装时，它们会吐出一些奇怪的日志 .

这是在终端中运行node-red时显示的日志 .
