@sdetweil – Thanks, Sam. It looks like I intended to send bme280.py but actually copied MMM-BME280.js. I see below where Ralf did post it, so I will look at that, too.

Kristian - do the links to the modules listed as numbers 7-10 need some validation? :)

@sdetweil - Thanks for the help here and offline. My problem is solved, and for the sake of others following is the resolution.

Problem: MagicMirror install script outputs node.js errors on new RaspbianOS install running under VirtualBox.

Diagnosis [by sdetweil]: “so, the problem is that the intel raspian is a hybrid, x86_64 kernel with a i386 user runtime.
and they stopped making a nodejs for i386 after node 12”

Solution: Rebuilt the virtual machine using Ubuntu instead of RaspbianOS. [I’m sure any Debian or other Linux distribution would work just fine…]

Thanks again - I can now use this as a dev machine and spare myself the risks associated with fiddling with the production machine!

@sdetweil - Thanks Sam. Viewed from that perspective it makes perfect sense! I’ll see if I can put a vnc client back on my phone and do it that way.
