"FileNotFoundError" exception raised on Windows

[KelSolaar]

Hello,

Trying the installer on Windows (for a user that does not have administrator rights) and the installation fails:

C:\Users\foo-bar>rez-env python -- python C:\Users\foo-bar\Downloads\install-poetry.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\foo-bar\AppData\Roaming\Python\Scripts

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