Question

This is the exception generated when I try to install pyaudio using python's pip:

Answer 1

You are trying to compile pyaudio from source and on a Windows platform that often is more difficult than one would like.

The specific problem you have is that the compiler is trying to find the include file portaudio.h which you don't have because it isn't a standard Windows include file and it is apparently also not in the download package.

It's clear that the reason pip is attempting the compile, rather than doing a binary install, is that the most recent binary installs are for Python 3.6, and you have Python 3.7.

I suggest that you install Python 3.6 alongside your existing Python 3.7 so that you can get going with this module. There may be Python 3.7 bindings available in due course, and then again there may not. The PyPI page for this project hasn't been updated in over 2 years.
