I am new to Arduino. I have installed the latest ESP8266 core for my project but the version.h error still occur. I could not find any solutions yet. Help!

Looks like some kind of misunderstanding from the lib part, I think this should refer to core_version.h?
Blynk-Technologies/blynk-library@2bf72bf
Blynk-Technologies/blynk-library#432 brought this up before, but was closed

edit ...unless they meant to refer to this one

Yep, SDK one. Check your install once more! This should work just fine circa 2018
