Ok, my apologies, as I could NOT install the micropython-ssd1327-1.0.0
library because after I DID install micropython from here:

No I did not invoke as I didn't know that it had to be

It looks like the Adafruit_CircuitPython_SS1327 library can't be
installed then, and the micropython-ssd1327-1.0.0 library can't be used
due to micropython not being invoked???

It now seems that the said oled display can't be used with a raspberry
pi, as it needs the ssd1327 library.
