Official Install on Windows PowerShell failed on FileNotFoundError

I've been trying to update my 1.1.13 poetry install to 1.2.2 using the official doc but it failed.

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:

D:\AppData\Roaming\Python\Scripts

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

FileNotFoundError: [WinError 2] Le fichier spécifié est introuvable

and the error same occurs after poetry uninstall with both python 3.9.6 and python3.8.10

I now don't have poetry anymore on my computer 😢

Inizia da install-poetry.py, in particolare da Installer.run, Installer.install, make_env e VirtualEnvironment.make, quindi riproduci il comando PowerShell ufficiale con Python 3.9.6 e 3.8.10 su Windows. Controlla il percorso di creazione dell’ambiente virtuale e l’errore del subprocess; il lavoro è completato quando l’installazione documentata termina senza FileNotFoundError e Poetry viene ripristinato dopo la disinstallazione.
