Steps to reproduce

We will try to install python-niapy in Arch Linux distribution. We provide an animation.

$ docker run -it --rm archlinux:base-devel
# useradd -l -md /home/aur -s /bin/bash aur && passwd -d aur && echo 'aur ALL=(ALL) ALL' > /etc/sudoers.d/aur
# su aur
$ sudo pacman -Syyuq --noconfirm
$ cd ~
$ curl -LO https://aur.archlinux.org/cgit/aur.git/snapshot/python-niapy.tar.gz
$ tar -xvf python-niapy.tar.gz
$ cd python-niapy
$ makepkg -s --noconfirm

Further information about versions

$ pacman -Qs python

Expected behavior
Tell us what should happen.

Build successfully as before (~ 1 week ago).

Actual behavior
Tell us what happens instead.

We have this error, no idea how to proceed, I only looked both issues related 1 2.
