Error: Esp8266lib.h no such file or directory

Hi. Im doing my final year project now. The project is about pet feeder. I use arduino uno and wifi module esp8266. But when i compile the source code i got error which is esp8266lib.h no such file or directory. I hv tried many ways i found in google and youtube but it failed. Can someone tell me how to solve it? Thank you.

What is the Blynk lib version and the ESP core are you using ?
Try using ESP core 2.4.2 and Blynk Lib 0.6.0…
