  pinMode(ledPin, OUTPUT);
}

void loop() {
  // Turn the LED on
  digitalWrite(ledPin, HIGH);  
  delay(1000); // Wait 1 second

int ledPin = 2;

It is not D2 pin. It is GPOI2. If you want D2 use:

int ledPin = D2; //GPIO4

see pins_arduino.h for details

yes i can write my program but it doesn't run anything after that .

Need to pull GPIO0 to VCC (or disconnect, it must be pulled internally to vcc) and reboot esp.
