 ========================================================

原因：

与是否安装了  Visual C++ 14.0 or greater 无关。

 

 

========================================================

 解决方案：

直接用pip安装的pyaudio不支持3.7，所以在安装或import的时候会报错。
所以直接下载whl文件安装即可。

whl下载地址：

https://github.com/intxcc/pyaudio_portaudio/releases

切换到whl文件目录，直接用pip安装

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

>>> import pyaudio
Could not import the PyAudio C module '_portaudio'.

The official PyAudio 0.2.11 does not support Python 3.7+, and trying to install results in the error C1083: Cannot open include file: 'portaudio.h'.

However, there are unofficial wheels for PyAudio that support 3.7+.

If you are using the official version, you must use Python 3.6 with PyAudio 0.2.11.

See http://people.csail.mit.edu/hubert/pyaudio/

pip will fetch and install PyAudio wheels (prepackaged binaries). Currently, there are wheels compatible with the official distributions of Python 2.7, 3.4, 3.5, and 3.6.
