I have the same problem. Could you please help me to solve this?

I have followed the link you have provided and all goes as directed, but board type doesn't show ESP8266.

Open the arduino IDE, goto boards manager and search for 8266 (community version) and install it.

Thank you for your help. Before this i need to add http://arduino.esp8266.com/stable/package_esp8266com_index.json in Additional Board Manager URLs field in Arduino IDEs after that only ESP8266 will be shown in Boards Manager.
