Help installing pydPiper plugin

Hi, everyone!
In my case:

PiZero W v1.3
Volumio v 2.907 02/07/2021 (last)
( uname -a: Linux volumio 4.19.118+ #1311 Mon Apr 27 14:16:15 BST 2020 armv6l GNU/Linux)

Then I try to use:
sudo apt-get update
sudo wget -O volumio_install_from_zip.sh https://raw.githubusercontent.com/Saiyato/volumio-plugin-helper/master/volumio_install_from_zip.sh

sh volumio_install_from_zip.sh Saiyato volumio-pydpiper-plugin

And get:
<br>pydPiper-0.3-alpha/sources/musicdata_rune.py<br>pydPiper-0.3-alpha/sources/musicdata_spop.py<br>pydPiper-0.3-alpha/sources/musicdata_volumio2.py<br>pydPiper-0.3-alpha/utils/<br>pydPiper-0.3-alpha/utils/characters.py<br>pydPiper-0.3-alpha/utils/fontutil.py<br>pydPiper-0.3-alpha/utils/lmslist.py<br>#
