Can't install PyAudio on macOS, getting "library not loaded" error. Portaudio is installed

Question

I tried installing PyAudio on macOS Sonoma, with multiple Python versions. I have portaudio installed with brew, and tried rebooting. When I try to install PyAudio it fails to build wheel with an error, I think the highlight is dyld[14720]: Library not loaded: @rpath/libLTO.dylib.

I searched online, but couldn't find an answer. I have tried python3 -m pip install pyaudio --global-option="build_ext" --global-option="-I/opt/homebrew/include" --global-option="-L/opt/homebrew/lib" and LDFLAGS="-L$(brew --prefix portaudio)/lib" CFLAGS="-I$(brew --prefix portaudio)/include" pip install pyaudio, but those didn't seem to help.

Here is the full output:

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

Does anybody know a solution to this?

Answer 1

I fixed it by installing macOS on a separate volume, at the setup I restored everything from the old volume, except "Other files". Now all things relating to brew are deleted, so I installed brew, then python and portaudio. The PyAudio installation now works without an error.

Answer 2

I had a similar problem with another library. Try another version of python (eg 3.11 or 3.10), it may work.

3.12 is still not fully supported by many libs
