I've been trying to install librosa on my raspberry pi 3 model B for quite some time now.
my python version is 3.7.3.
pip version is 21.0.
operating system is the image from the official raspberry pi site of raspbian.
I've done:
sudo apt update/upgrade
so the os should be up to date.
what I do is:
python3 -m pip install librosa
I would really appreciate if anyone could help me understand the error message and maybe even fix it.
the error I get is:
