PiratePlayer on Pi 4 How to

I have a Pi 4 with Raspberry OS from 01.11.2021

I have added the PirateAudio 3Watt amp and want to install pirateplayer

Raspberry Pi OS Lite
Release date: January 11th 2021
Kernel version: 5.4
Size: 438MB

Do I need to install the dev environment to use Pirateplayer?

Pip is installed
pip3, too.
python3, too.

when i use
sudo pip install pirateplayer

I get

Looking in indexes: //pypi.org/simple, //www.piwheels.org/simple
Collecting pirateplayer
Could not find a version that satisfies the requirement pirateplayer (from versions: )
No matching distribution found for pirateplayer

And the command for gstreamer on their page

apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio

is not working properly.

I installed every package, instead of gstreamer1.0-qt5 because that does not work. Any suggestions?

Thanks for answer
