You need to give us more information in one post otherwise this game could go on a long time.

  1. Have you tried rebooting?

  2. If yes, what are you running Node-RED on? What version? What version of nodejs?

  3. You mention 2 different nodes Node-red-node-arduino and node-red-contrib-gpio but only talk about one window

the window prompts cannot read property 'on' of null.

So what node are you using? When does it give you that error message? How have you got the node configured?

7

yes，reboot.
node-red: v1.0.1
node.js:v10.0.0
The node-red-node-arduino is installed,but the node is not shown on the bread.And window prompts Missing serialport dependency.I had this problem at night.

How did you install Node-RED v1.0.1?

Have you tried reinstalling node-red-node-arduino?
Are there any error messages when you reinstall?

9

Running with windows7,take advantage of npm install -g --unsafe-perm node-red.
Rebooted several times

10

Try reinstalling node-red-node-arduino
Are there any error messages when you reinstall?

Uninstall does not come off,because the page does not show the option to remove

I didn't ask you to uninstall it.

But I don't have time to keep up with the same issue in multiple threads. Good luck is finding the solution.
