Problem
Today I installed pyaudio on my new Linux laptop (a python package for sound recording), I encountered an error I never met:
Building wheel for pyaudio (pyproject.toml) ... error
error: subprocess-exited-with-error

note: This error originates from a subprocess, and is likely not a problem with pip.

ERROR: Could not build wheels for pyaudio, which is required to install pyproject.toml-based projects
Solution
We can focus at the compile error: 9 | #include “portaudio.h”, it means the current system may lack some related libraries.
After searching the discussions of stackoverflow, I installed the portaudio19-dev and it will install the PortAudio development files and the head file portaudio.h.
sudo apt install portaudio19-dev
And then, we can try to install pyaudio package again. I think it will be fine!
pip3 install pyaudio
