exit status 1

Error compiling for board NodeMCU 1.0 (ESP-12E Module).

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

You might using ESP8266 3.x version. Try changing it to ESP8266 2.7.x. Go to tools -> Board manager, then find ESP8266 by esp8266 community
