This "Official Installer Script" fails on Windows

Installed on an up-to-date vanilla Windows 11 machine with Python 3.13 (symlinks enabled), via the official method recommended right here on the website:

PS C:\Users\me> (Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py -
Retrieving Poetry metadata

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.

It will add the `poetry` command to Poetry's bin directory, located at:

C:\Users\alexander.chandel\AppData\Roaming\Python\Scripts

You can uninstall at any time by executing this script with the --uninstall option,
and these changes will be reverted.

Installing Poetry (1.8.4)
Installing Poetry (1.8.4): Creating environment
Installing Poetry (1.8.4): Installing Poetry
Installing Poetry (1.8.4): Creating script
Installing Poetry (1.8.4): Done

Poetry (1.8.4) is installed now. Great!

To get started you need Poetry's bin directory (C:\Users\me\AppData\Roaming\Python\Scripts) in your `PATH`
environment variable.

Alternatively, you can call Poetry explicitly with `C:\Users\me\AppData\Roaming\Python\Scripts\poetry`.

You can test that everything is set up by executing:

`poetry --version`
PS C:\Users\me> C:\Users\me\AppData\Roaming\Python\Scripts\poetry --version
PS C:\Users\me>

Ok so the installation failed somehow. Calling it explicitly outputs nothing. And it did not bother to add that dir to my USER PATH for me, so it isn't really an "install". Let's add it to the PATH and try again:

PS C:\Users\me> poetry --version
PS C:\Users\me> poetry -h
PS C:\Users\me> poetry -foobar
PS C:\Users\me>

No output at all, literally nothing.

Let's try the absolute path, just in case:

PS C:\Users\me> C:\Users\me\AppData\Roaming\pypoetry\venv\Scripts\poetry.exe --version
PS C:\Users\me> C:\Users\me\AppData\Roaming\pypoetry\venv\Scripts\poetry.exe -h
PS C:\Users\me>

Still nothing. What's going on?

Inizia riproducendo il comando ufficiale dell’installer riportato nell’issue su Windows 11 con Python 3.13, quindi ispeziona l’entry point dell’installer all’indirizzo https://install.python-poetry.org e l’eseguibile Poetry generato. Il lavoro è completato quando l’installazione produce un output utilizzabile di poetry --version e il comando documentato o la configurazione di PATH funzionano come descritto.
