I cannot install Yaourt: I do not have write permission for the directory

Question

These are the instructions (https://manjaro.site/how-to-install-yaourt-on-arch-linux/) to install Yaourt:

git clone https://aur.archlinux.org/package-query.git 
cd package-query 
makepkg -si 
cd .. 
git clone https://aur.archlinux.org/yaourt.git 
cd yaourt 
makepkg -si

I successfully run the first two lines, but when running makepkg I get the error:

=> ERROR: You do not have write permission for the directory $BUILDDIR (/home/pietrom/package-query).
    Aborting...

I try with:

sudo makepkg -si

and I get this error:

==> ERROR: Running makepkg as root is not allowed as it can cause permanent, 
catastrophic damage to your system.

I change the file's owner:

sudo chown pietrom ./PKGBUILD
sudo chgrp users ./PKGBUILD

and, again, I get:

makepkg -si
==> ERROR: You do not have write permission for the directory $BUILDDIR (/home/pietrom/package-query).
Aborting...

What am I doing wrong?

I havo to install Yaourt to install Google Chrome.

Make sure that you are not typing sudo in front, like this:

sudo git clone https://aur.archlinux.org/yaourt.git

Instead, type:

git clone https://aur.archlinux.org/yaourt.git
