Looks like you need to install the GFX library:
https://github.com/adafruit/Adafruit-GFX-Library
(Or it's downloaded, but incorrectly named or not placed in the right location. But since you have the LEDBackpack library properly installed, I'm guessing that's not it.)

Every Arduino display we carry relies on two libraries. The first is a hardware-specific library that contains functions unique to each device, while the second (Adafruit_GFX) contains higher-level graphics primitives (lines, circles, etc.) that can be shared in common across all devices.

The mistake was mine. I didnt understand what they meant by sketchlibrary. after reading you reply I check the tutoary how to add a library on arduino. the next challenge is nothing is happening after I upload the sample code. I have a picture of my circuit. please help.

It's difficult to see, but it appears in the picture that you have FLORA GND connected to SDA and and FLORA SDA connected to GND. Is that true?
