推荐答案
PyAudio 当前可用于Python 2.7和3.4-3.6.如果您不想使用Python 3.6并想在3.7中安装PyAudio，则必须从源代码编译并安装PortAudio和PyAudio.请参阅说明
Prebuilt wheels of PyAudio are currently available for Python 2.7 and 3.4-3.6. If you don't want to use Python 3.6 and want to install PyAudio in 3.7 you have to compile and install PortAudio and PyAudio from sources. See the instructions at
