我一直在开发一款基于 Pygame 的打字速度测试游戏。我尝试运行代码，但我不断收到此错误：
Traceback (most recent call last):
File "/Users/beatricecesonyte/Downloads/python-project-typing-speed-game/speed typing.py", line 170, in <module>
Game().run()
File "/Users/beatricecesonyte/Downloads/python-project-typing-speed-game/speed typing.py", line 30, in __init__
self.open_img = pygame.image.load('type-speed-open.png')
pygame.error: File is not a Windows BMP file

我尝试根据此错误查看其他问题，但似乎没有任何效果......
我使用的是 macOS Catalina、Python 3.8.5 和 Pygame 1.9.6。
我目前不是Python专业人士，所以请尽量解释清楚！
谢谢！
您的图像是
PNGBMPBMPPIL你可以像这样测试你的pygame是否支持png：
>python
>>> import pygame
>>> pygame.image.get_extended()
如果返回 False，则说明没有返回，您需要使用对 .png 文件的 SDL 图像支持构建的 Python。我在 Mac 上也遇到了这个错误，对我来说有效的方法很简单：
pip uninstall pygame
pip install pygame --force-reinstall --no-cache-dir
