Have you meticulously installed all the extensions as shown here?

Thank you.
I installed "PlatformIO IDE" followed that link, do you mean all others IDE ?

I wanted to know if you had installed PlatformIO and ESP32/ESP8266 Libraries on PlatformIO IDE. Looks like you have done everything. The error that you have mentioned in your question usually occurs when a library is missing.
