在 3.5" 屏幕上的树莓派零上运行 pygame 脚本时遇到问题

Question

Im trying to run my test game-script written in pygame on my raspberry pi zero w on a 3.5" LCD screen (which is working).

But I keep getting this error. And I haven't after ALOT of hours found a fix for this, does anyone know how to fix this? Im running the latest version of Raspberry Pi OS lite

Script:

import pygame

pygame.init()
win = pygame.display.set_mode()

x = 50
y = 50
width = 40
height = 60
velocity = 10

run = True 
while run:
    pygame.time.delay(100)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False


    keys = pygame.key.get_pressed()

    if keys[pygame.K_LEFT]:
        x -= velocity

    if keys[pygame.K_RIGHT]:
        x += velocity

    if keys[pygame.K_UP]:
        y -= velocity

    if keys[pygame.K_DOWN]:
        y += velocity



    win.fill((0, 0, 0))
    pygame.draw.rect(win, (255, 0, 0), (x, y, width, height))
    pygame.display.update()


pygame.quit()```

I think you need to include your params in win = pygame.display.set_mode() like this: win = pygame.display.set_mode(size=(x,y), width=width, etc...)

You will need to declare those variables before win = pygame.display.set_mode()

Are you executing from terminal or IDE? Do you have one or more displays?
