I have tried downloading Visual Basic Tools, as well as, I have tried doing the pip install pipwin and then PyAudio function. But unfortunately the same error occurred. I also tried downloading the following and installing it: PyAudio‑0.2.11‑cp39‑cp39‑win_amd64.whl

I am trying to build an Alexa-like AI, and need this PyAudio package.

Answer 1

Perhaps try pip install pipwin and then pipwin install pyaudio ? pipwin is designed to work on Windows, so you may have better luck with it.

Answer 2

As of today 10-03-2022, you have following options:

• use python 3.6 (wheels available), probably you don't want to give up on the latest python version because of this dependency, but this is an easy option.
• you build it from source, probably will take you some effort.
• you download the wheel package from gohlke's page and tell pip to use that wheel instead of downloading it from pypi.
