ValueError: incompatible .mpy file

[fanlessfan]

I got error when I try to import ina219.mpy in a ESP8266 broad. (D1 mini)

Traceback (most recent call last):
File "", line 1, in
ValueError: incompatible .mpy file

Sorry I should have deleted the .mpy files a long time ago, they are not portable between versions of micropython and I would have to build and maintain a load of versions. You can build them yourself as explained in:
https://github.com/micropython/micropython/tree/master/mpy-cross

Quickest way to get going is probably docker image mentioned in:
https://github.com/micropython/micropython/tree/master/ports/esp8266
