解决方案：

1.在尝试安装 pyaudio 时遇到的错误信息表示安装过程失败，原因是找不到 Python.h 头文件。这通常意味着你的系统上缺少 Python 开发包。Python.h 文件是 Python 开发文件的一部分，对于那些包含 C 扩展的包（比如 pyaudio）来说是必需的。

如果你的Ubuntu版本较新，可能需要安装的是 python3-dev：

sudo apt-get update

sudo apt-get install python3-dev

2.要解决这个问题，你需要在Linux系统上安装相应的Python开发包。因为你使用的是Python 3.8，可以通过包管理器来安装所需文件。如果你使用的是基于Debian的系统（比如Ubuntu），可以这样做：

sudo apt-get update

sudo apt-get install python3.8-dev

3.再次安装pip3 install pyaudio 成功
