写在前面

自己的测试环境：

在 Ubuntu 使用$ pip install pyaudio 进行安装 pyaudio 出现如下报错：

bash 复制代码

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for pyaudio

ERROR: Could not build wheels for pyaudio, which is required to install pyproject.toml-based projects

二、解决方法

首先安装依赖库：

bash 复制代码

# 有些人说执行下面一条指令即可
sudo apt-get install portaudio19-dev
# 如果不成功，就尝试下面这条指令
sudo apt-get install libasound-dev portaudio19-dev libportaudio2 libportaudiocpp0

然后，再次进行安装：

bash 复制代码

pip install pyaudio
