Can't install aubio library for python

Question

I've had this problem for hours, and still can't fix it. I've tried almost everything.
I've tried using both python 3.10 and 3.8 and here is the error I usually get:

  note: This error originates from a subprocess, and is likely not a problem with pip.

Answer 1

if you are using a unix based system try installing the aubio / python-aubio package from your system package manager or app store.

Arch: sudo pamac -Syu aubio

Ubuntu: sudo apt-get install aubio

Note: this will install aubio globally. Since you can't install aubio directly with pip, I suggest as a workaround creating a virtualenv cloning your system packages. Just run: python -m venv venv_name --system-site-packages
