The sketch does not compile 1.8.8

When just compiling the example, the Arduino compiler returns an error:
WARNING: library e-ink-master claims to run on (AVR) architecture(s) and may be incompatible with your current board which runs on (avr) architecture(s).

I think there may be some problems in the development environment you installed.
Maybe it is not correctly introduced into the Arduino.
Please tell me if there is still a problem with the compilation failure.
