I'm not able to install it on Node Red running into a Raspberry Pi 4

Can you try the following solution? It fixed it for me on Ubuntu 18.04.

Clone the repo
In the file "package.json" replace the following lines

"dependencies"  : {
        "serialport"   : "^6.2.0"
    },

for the following (I use serialport version 7.7.6. Change it to whatever version your using)

"dependencies"  : {
        "serialport"   : "^7.7.6"
    },

Build locally with

npm install ~/path/to/repo/node-red-contrib-dmxusbpro
