platformio.ini contents:

board = heltec_wifi_kit_8
;upload_protocol = esptool

Similar questions have pointed to multiple instances of PIO but PIO isn’t present in the system python.

Any ideas?

You have not selected a framework in the PlatformIO, so it probably hasn’t registered any internal handlers for the compilation process. If you want to use Arduino, just add

framework = arduino

to the platformio.ini, together with a main.cpp with the minimal functions setup() and loop() of course.

Or are you attempting to do a bare-metal build for the ESP8266 without any frameworks?

That was exactly it and in retrospect that should have been obvious… Many thanks! (Trying to migrate my experimental workflows from the regular Arduino IDE to PIO)

Maybe this needs a more helpful error?
