如何解决无法打开image.png

我试图创建一个太空侵略者游戏，但无法打开图片 这是代码

import pygame

# Inizialize the pygame
pygame.init()

#create the screen
screen = pygame.display.set_mode((800,600))

# Title and Icon
pygame.display.set_caption('Space Invaders')
   
#Player
playerImg = pygame.image.load('space-invaders.png')
playerX = 370
playerY = 480

def player():
    screen.blit(playerImg,(playerX,playerY))

#Game Loop
running = True
while running:

    #RGB - red,green and blue
    screen.fill((0,0))

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

    player()
    pygame.display.update()

这是确切的错误：

Traceback (most recent call last):
  File "SpaceInvaders/main.py",line 20,in <module>
    playerImg = pygame.image.load('space-invaders.png')
pygame.error: Couldn't open space-invaders.png
