Help needed installing Library for SPI Colour LCD

    I have never had any problems installing SW for previous Pimoroni products but I can't get my latest purchase (1.3" SPI Colour LCD display) to work on my new Raspberry Pi 400. I believe I have followed all the instructions given and get positive confirmation from the install process but when I try to run any of the examples I get a ModuleNotFoundError error. Since this is not a new product I expect I must be doing something wrong. After multiple tries and resets, an example session is listed below.

Any ideas gratefully received.

Make sure SPI is enabled.

(I’ve reformatted your shell output for clarity, because the problem becomes very obvious when readability is assured. In future, please wrap such output as “Preformatted text”, by selecting the entire block and clicking on the </> icon in the editor toolbar.)

It seems you installed the ST7789 module under Python 2, but are running your scripts with Python 3, so ModuleNotFoundErrors are to be expected.

Run:

sudo pip3 install st7789

then try your scripts again.
