I’m trying to use the MMM-Gesture module, but the following errors continue to occur.
I need everyone’s help.

I uploaded the .ino file in the Arduino folder and modified it to /dev/ttyACM0 instead of /dev/ttyACM0* in the 104th line of the Node_helper.js file.
And when I ran the magic mirror, there was another error.
I don’t know what the problem is yet.

Arduino’s serial window was open, so this created an error.
In conclusion, it was an error that was resolved by uploading the .ino file in the Arduino folder.
I hope this documentation will help others.
