_ [mac][python] PyAudioをインストールしようとしたらエラーがたくさん出る

最近流行ってるじゃん？機械学習だAIだディープニューラルネットワークだフェデレーテッドラーニングだ，と．で，なんでかよくわからないけど流れで音声解析することになってmacで環境作ろうとしたら，ふむなるほどとりあえずPyAudioをインストールしてみっか，ってなったらエラーがうわーってでてくる． 具体的にはこんな感じ．

まあようするにportaudioをインストールしろよってのと，portaudio.hが見つかってねえこのぼんくらっていうエラーメッセージなのね． そうですかportaudioを入れればいいのね？

% brew install portaudio

ってするとあっさりportaudioは入る．だから

% pip install pyaudio

って続けて打つとまた同じエラー．．

とりあえずportaudioがインストールしたportaudio.hを見つけて，そのリンク先ライブラリも指定するかってなって

% sudo env LDFLAGS="-L/opt/homebrew/Cellar/portaudio/19.7.0/lib" CFLAGS="-I/opt/homebrew/Cellar/portaudio/19.7.0/include" pip install pyaudio
