在 Google Colab 上安装 pyaudio 失败，出现“错误：pyaudio 的构建轮失败”

Question

尝试在 Google Colab 上安装 pyaudio，但出现错误“错误：pyaudio 的构建轮失败”。

!apt install libasound2-dev portaudio19-dev libportaudio2 libportaudiocpp0 ffmpeg libav-tools
!pip install pyaudio

我收到此错误：

Answer 1

我只需要删除libav-tools的apt install，然后再次运行此命令。

!apt install libasound2-dev portaudio19-dev libportaudio2 libportaudiocpp0 ffmpeg

现在pyaudio安装成功。
