Hi Hiroyoki,I checked and I was able to compile under Arduino 1.8.3 with SparkFun Micro OLED 1.2.0 library.I than upgraded all libraries to newest including arduino to 1.8.5 and I was able to compile that example program without errors. Try installing that SparkFun Micro OLED library from library manager.I am running that same devices on photo now for more than year and they work OK, hopefully you will manage to compile after you install that library.Let me know if installing library helped.Miro
