pygame.error:字体未初始化如何修复？

import pygame

# 初始化pygame
pygame.init()

# 初始化字体模块
pygame.font.init()

# 设置窗口大小
window_width = 800
window_height = 600
window = pygame.display.set_mode((window_width, window_height))

# 加载字体文件
font_path = "path/to/font.ttf"
font_size = 24
font = pygame.font.Font(font_path, font_size)

# 渲染文本
text = font.render("Hello, World!", True, (255, 255, 255))

# 在窗口上绘制文本
window.blit(text, (window_width/2 - text.get_width()/2, window_height/2 - text.get_height()/2))

# 更新窗口显示
pygame.display.flip()

# 游戏主循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

# 退出pygame
pygame.quit()
