Make sure that you have an installed <ArduinoJson.h> library . Or try installing it from here : https://arduinojson.org/doc/installation/
Honestly I don't know much about it since I've never come across such an error .
But try looking for it at
Or here http://www.esp8266.com/viewtopic.php?p=55673
Basically these two libraries are inbuilt libraries . When you change the board to ESP8266 these are found . If you can't find it , go to library manager in Arduino IDE and search ESP8266 you get all the supporting libraries . If nothing helps , go here https://github.com/esp8266/Arduino/tree/master/libraries and download as you need and add as zip
