I am trying to install PyAudio for a project. I have added the path of my python installation C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64 and the Scripts subfolder. I am running an elevated CMD instance. I type: pip install PyAudio. The build process begins. below is the output:

From what I understand, the wheel cannot be built because _portaudiomodule.c is trying to include portaudio.h, which doesn't exist for some reason.

After failing to build the wheel, pip then tries to run setup.py, which again calls portaudiomodule.c, which again cannot include portaudio.h.

Is this an error with the package on pypi.org or with my installation of pip?

Python 3.7.5, installed under Visual Studio Community 2019. Windows 10 Home

It looks like there's an issue with the version in PyPi. (See also this answer)

The maintainers of PyAudio haven't built it for python 3.7 running on Windows, so your system is trying to compile it, and fails.

If you have access to Python 3.6 you should be able to install from PyPi on there.

It looks like the best way to get it working on Python 3.7 is to use the pre-built wheels from Christoph Gohlke

Edit: updating with installation instructions (reference)

You'll want the wheel specific to your version and build of python (3.7, 64-bit) so you'll want to download PyAudio‑0.2.11‑cp37‑cp37m‑win_amd64.whl

Then provide that file to pip e.g. 

pip install C:\Users\AwsesomeCronk\Downloads\PyAudio‑0.2.11‑cp37‑cp37m‑win_amd64.whl

If Visual Studio is doing anything funny with your environment, like hiding system files, you may need to copy the .whl file over into your project directory and install from there.
