Cannot install a new version of poetry after uninstall an older one

[MadJlzz]

I am actually facing a problem reinstalling poetry after uninstalling the current version from my system:

python .\install-poetry.py --uninstall

The idea was to try and play with one pre-release version: 1.2.0a2`

To install it, I simply do:

python .\install-poetry.py --version 1.2.0a2

The process seems to be blocking and I have no idea why:

PS C:\Users\julie> python .\install-poetry.py --version 1.2.0a2
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\julie\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 (1.2.0a2)
Installing Poetry (1.2.0a2): Creating environment
Installing Poetry (1.2.0a2): Installing Poetry

I am working on Windows 10 with Python 3.9.6

Also, it is worth mentionning that I cannot get back to an older version like 1.1.8 as it blocks the same way.

Anyone facing the same issue?

Found the issue. I was messing around with my pip.conf file by specifying a new registry and it wasn't accessible. Because poetry might use pip under the hood in other threads, no error message was able to pop up.

Hope it helps other people.
