Pyaudio 在 Ubuntu 上安装失败

Question

Pyaudio 在 Ubuntu 上安装失败我有 ubuntu 18LTS python 2 和 python 3 pip 10

我根据在谷歌上找到的建议安装了 libportaudio2 和 libasound-dev。是不是因为我还需要安装其他库？

这是我尝试使用 sudo -H 标志但没有区别的错误。

sudo python -m pip install pyaudio

Answer 1

致命错误：portaudio.h：没有那个文件或目录

您缺少一些构建依赖项，因此编译失败。具体来说，错误显示它找不到portaudio.h，随portaudio19-dev包一起提供。

所以安装所需的头文件：

sudo apt-get install portaudio19-dev

然后尝试您的 pip 安装。

Answer 2

你可以试试

sudo apt-get install python-pyaudio

在安装软件包之前尝试一下：

sudo apt-get install portaudio19-dev

如果上述建议不起作用：

sudo apt-get install libjack-jackd2-dev portaudio19-dev

并且pip install pyaudio应该有效。
