Python Pygame-否“；混合器；模块发现

我想用pygame在我的raspberry pi上播放音频文件。 当我执行此代码时：

import pygame
pygame.mixer.init()
pygame.mixer.music.load("/home/pi/Greetings/Welcome to the game.mp3")
pygame.mixer.music.play()

我得到一个错误：

  File "try.py", line 14, in <module>
    pygame.mixer.init()
  File "/home/pi/visionbeyond_test/env/lib/python3.7/site-packages/pygame/__init__.py", line 59, in __getattr__
    raise NotImplementedError(missing_msg)
NotImplementedError: mixer module not available (ImportError: libSDL2_mixer-2.0.so.0: cannot open shared object file: No such file or directory)

我猜我特别需要安装

libSDL2\u mixer-2.0.so.0

，但我尝试使用pip进行安装，但它找不到任何具有该名称的软件包。 我正在为所有软件包使用虚拟环境，因此请牢记这一点，让我知道如何尽快解决问题

Python版本：

3.7.3

经过大量挖掘，我找到了适合我的解决方案

只需执行以下命令：

apt-get install git curl libsdl2-mixer-2.0-0 libsdl2-image-2.0-0 libsdl2-2.0-0

我仍然不明白它是如何工作的，因为我已经有了那些软件包
