Retrieving Poetry metadata

This installer is deprecated. Poetry versions installed using this script will not be able to use 'self update' command to upgrade to 1.2.0a1 or later.
# 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:

%USERPROFILE%\.poetry\bin

This path will then be added to your `PATH` environment variable by
modifying the `HKEY_CURRENT_USER/Environment/PATH` registry key.

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

Installing version: 1.1.12
  - Downloading poetry-1.1.12-win32.tar.gz (51.60MB)

Poetry (1.1.12) is installed now. Great!

To get started you need Poetry's bin directory (%USERPROFILE%\.poetry\bin) in your `PATH`
environment variable. Future applications will automatically have the
correct environment, but you may need to restart your current shell.
