环境信息 #

• MacOS 10.14 (Mojave)
• Python 3.9.6
• Pygame 2.4.0
• PyCharm + 虚拟环境(Venv)

已尝试操作 #

• 确认虚拟环境中存在libmp3lame.0.dylib文件
• 重新安装Pygame

解决方案 #

方案1：降级Pygame到兼容Mojave的版本

Pygame 2.2及以上版本的预编译包使用了MacOS 10.15+才支持的加载命令（load command 0x80000034），Mojave无法识别。降级到2.1.3版本可解决：

# 卸载当前版本
pip uninstall -y pygame
# 安装兼容版本
pip install pygame==2.1.3

方案2：从源码编译Pygame（依赖Homebrew）

如果需要使用高版本Pygame，可通过源码编译适配Mojave：

1. 安装依赖库：

brew install sdl2 sdl2_mixer sdl2_image sdl2_ttf sdl2_gfx libmp3lame

2. 卸载现有Pygame：

pip uninstall -y pygame

3. 从源码安装：

pip install pygame --no-binary pygame

方案3：验证Python环境兼容性

确保Python 3.9.6是针对MacOS Mojave编译的。如果是从Python官网下载的安装包，需确认是支持10.14的版本（Python 3.9最后支持Mojave的版本是3.9.13）。若当前Python版本存在兼容性问题，可尝试降级到Python 3.8.x。
