Why do I get "HTTP Error 404: Not Found" when installing pyaudio with pipwin in Python Django project in Windows 10?

Question

I'm trying to install pyaudio with pipwin in a Python Django project in Windows 10.

I first run CMD as admin in Windows 10. Then I run the command:

pipwin install pyaudio

and I get the following error:

raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 404: Not Found

the full output from the command:

Why can I not install pyaudio?

Thanks!

Update

I tried running this command now (pipwin´ doesn't seem to have the --no-cache-dir option`):

pip install pyaudio --no-cache-dir

and get the following error(s) and output:

WARNING: You are using pip version 20.3.3; however, version 21.0.1 is available.
You should consider upgrading via the 'C:\Users\...\Documents\django\...\Scripts\python.exe -m pip install --upgrade pip' command.

Answer 1

This is a problem not necessarily related to pyaudio. Try:

pipwin refresh

and then install what ever you want using pipwin.
