Python速成班空间入侵者问题

Question

我已经谈到了在python上创建空间入侵者的问题。这是我的密码。我有一个回溯错误：

File "C:\Users\Deadl\Desktop\py4e\Python Crash Course 5\spaceinvader.py", 
    line 27, in <module> run_game()   
File "C:\Users\Deadl\Desktop\py4e\Python Crash Course 5\spaceinvader.py", 
    line 14, in run_game
    ship = Ship(screen)    
File "C:\Users\Deadl\Desktop\py4e\Python Crash Course 5\ship.py",
    line 7, in __init__    
    self.image = pygame.image.load('images/ship.bmp')
pygame.error: Unsupported image format

有人能帮我吗？我已经检查了我的飞船和设置，它们都正常。我在我的空间入侵文件夹中创建了一个图像文件夹，其中ship图像为ship.bmp

import sys
import pygame
from settings import Settings
from ship import Ship

def run_game():
    #Initialize the game and creates a screen object.
    pygame.init()
    ai_settings = Settings()
    screen = pygame.display.set_mode(
        (ai_settings.screen_width, ai_settings.screen_height))
    pygame.display.set_caption("Alien Invasion")
    # Make a ship.
    ship = Ship(screen)
    # Start the main loop for the game.
    while True:
        #Watch for keyboard and mouse events.
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()
        # Redraw the screen during each pass through the loop.
        screen.fill(ai_settings.bg_color)
        ship.blitme()

        # Make the most recently drawn screen visible.
        pygame.display.flip()
run_game()
