when installing pyaudio, pip cannot find portaudio.h in /opt/homebrew/Cellar/portaudio/19.7.0

Question

Before I start the question, I tried to solve issue with this post, but it did not work: (Link)

I am using mac (M1 air). I tried to install pyaudio, so I ran pip install pyaudio. Then, I got the following error about not finding portaudio.h:

pip install pyaudio

So, After some research I tried to install and link portaudio first like this:

brew install portaudio
brew link portaudio
pip install pyaudio

Since brew link portaudio returns Warning: Already linked: /opt/homebrew/Cellar/portaudio/19.7.0, I expected that portaudio was installed succesfully and pyaudio should have no issue with portaudio.h file. However, even after installing it, and after explicitly setting the path to the portaudio folder, the pip install command still returns this error.

Here is the pip commands I tried (they all return the same error):

pip install pyaudio
pip install --global-option='build_ext' --global-option="-I$(brew --prefix)/include" --global-option="-L$(brew --prefix)/lib" pyaudio
pip install --global-option='build_ext' --global-option='-I/opt/homebrew/Cellar/portaudio/19.7.0/include' --global-option='-L/opt/homebrew/Cellar/portaudio/19.7.0/lib' pyaudio

Has anyone had similar issue and solved it before when installing a python module with some c-lang file?

Answer 1

I think a fix is coming soon. In the meantime, you should be able to workaround the issue by doing this:

export CFLAGS="-I/opt/homebrew/include"
export LDFLAGS="-L/opt/homebrew/lib”
pip install pyaudio

Good luck!

Answer 2

Some suggestions:

Try the answer provided here. It suggests you use --no-binary: all: like so:

sudo pip3 install pyaudio --no-binary :all:

Or:

python -m pip install --upgrade pip
python -m pip install --no-use-pep517 pyaudio

The other option is to downgrade pip. While I haven't used pyaudio before, I have gotten this error with other libraries and one of the above solutions usually fixed it. There is a good possibility that these won't work for you, and there are a lot of different ways this issue can be fixed that are mentioned in SO. One of those solutions will eventually work for you.
