can't get this compiled anymore

[barnosch]

Hi, sadly i killed my ESP8266 with my working beloved Wordclock.
Sadly my old Laptop with a working copy of all the correct libraries and the sketch does not live anymore, aswell.

With a new installed Arduino IDE 2 i do not get this compiled anymore.
"NtpClientLib" thors the error but i guess of the ESP8266 package?

is the error. I tried all the different Versions of the lib.

Do you have maybe the correct libraries or can give me a hint?
