Unable to install on Ubuntu Unity 23.04

Hello,

The install command mentioned in the README is : pip install dtrx.

Obviously, when running it on a frenshly installed distro, it outputs this :

Command 'pip' not found, but can be installed with:
sudo apt install python3-pip

But after executing that command then retrying the first one, a new message, one that I never encountered before, appears :

rror: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.

    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.

    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.

    See /usr/share/doc/python3.11/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

So I run sudo apt install pipx then pipx install dtrx, which leads me to the following output :

The above exception was the direct cause of the following exception:
