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）在Node-Red中安装arduino节点无济于事。节点标记为安装在＆＃34;管理托盘中。选项卡，但它被禁用并拒绝启用它自己。我试图插入上面链接的示例代码，但Node-Red没有识别它。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
> serialport@4.0.3 install /home/myusername/.node-red/node_modules/serialport
> node-pre-gyp install --fallback-to-build

以下是在终端中运行node-red时显示的日志。
