如何修复外星入侵文件中pygame的ImportError“库未加载”？

Question

这是我的代码：

import sys
import pygame

class AlienInvasion:
    """Overall class to manage game assets and behavior"""

    def __init__(self):
        """Initialize the game, and create game resources."""
        pygame.init()

        self.screen = pygame.display.set_mode((1200,800))
        pygame.display.set_caption("Alien Invasion")

    def run_game(self):
        """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()

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


if __name__ == '__main__':
    # Make a game instance and run the game
    ai = AlienInvasion()
    ai.run_game()

我已经通过mac上的终端安装了pygame。 当我试图运行我的代码时，它给了我下面的错误。 我期待着一个空白屏幕。 我试过pip uninstall pygame和pip install pygame，但没有成功。 如果有人能帮忙，那就太好了
