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?

Commencez par reproduire la commande officielle de l’installeur indiquée dans l’issue sous Windows 11 avec Python 3.13, puis inspectez le point d’entrée de l’installeur à l’adresse https://install.python-poetry.org et l’exécutable Poetry généré. C’est terminé lorsque l’installation produit une sortie utilisable de poetry --version et que la commande documentée ou la configuration de PATH fonctionne comme décrit.
