一、Windows

https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio

pip install PyAudio-0.2.11-cp37-cp37m-win_amd64.whl

装错wheel会报错：

ERROR: PyAudio-0.2.11-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform.

python shell中输入：

>>> import wheel.pep425tags as w
>>> print(w.get_supported())
