Error compiling for board Arduino/Genuino UNO

Hi guys,
I'm trying to get my TFT LCD working using the Arduino library, I followed this example for printing a text. But when I'm about to compile, it gives the error "Error compiling for board Arduino/Genuino UNO".
Here's the complete error:

 class Adafruit_ST7735 : public Adafruit_GFX {
       ^

Error compiling for board Arduino Esplora.

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

(I deleted part of the log because it exeeded the characters limit of 9000)

and here's my code

#include <SPI.h>
#include <TFT.h>

#include <Adafruit_ST7735.h>
#define cs    10
#define dc    9
#define rst     8
TFT screen = TFT(cs, dc, rst);
char stuff[4];

void setup() {
  pinMode(cs, OUTPUT);
  schermo.begin();
  schermo.background(0, 0, 0);
  schermo.stroke(255,255,255);
  schermo.setTextSize(5);
  schermo.text("hey",0,0);
  

}

Also, I didn't understand why I need to create an array to print a text
Thanks in advance

here's my code

but not all of it.

Oh, right, lol.
Btw the void loop is empty, because i just need to print "hey" and stop. Do i need to do something more?

Sorry, I didn't made attention posting. At first, I thought that maybe these library only works on boards like Leonardo or the Esplora (or maybe for the UNO I need changements) so I tried compiling it changing the board, but the result was still the same.
By the way, my LCD isn't official, is from Adafruit. Is that the same?
