Hello - I've been developing my node-red flows an a RPi3+ with great success, but have recently had to change hardware to reduce power consumption. When I swap my SD card to a Raspberry Pi Zero W node-red fails to start and shows the following messages in the command window.

The same SD card put back into the RPi3+ boots and runs as expected. Any thoughts?

The Pi Zero and Pi3 are different architectures that require different node binaries.
