Installation after Deinstallation impossible

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: linux mint 19.3

• Poetry version: master / 1.0.9

Issue

I installed poetry with the curl pipe command which resulted in an installation with python2.7. I got sick of the version message every time and wanted to reinstall with python3.

To safe some time I modified the install command for uninstallation: curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python - --uninstall

The uninstallation went through without a problem. Then I wanted to install poetry again with py3 but it is not possible anymore regardless of the python version (I tried 2.7, 3.5, 3.6, 3.7, 3.8, 3.9).

Next I tried to recreate the problem on another machine which resulted in the same issue. I first installed poetry, then uninstalled it and tried to install again. See below for the outputs of those three commands.

EDIT: I installed py3.9 after the uninstallation. System is up-to-date.

$ curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python3
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:

$HOME/.poetry/bin

This path will then be added to your `PATH` environment variable by
modifying the profile file located at:

$HOME/.profile

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

Installing version: 1.0.9
  - Downloading poetry-1.0.9-linux.tar.gz (25.37MB)

Poetry (1.0.9) is installed now. Great!

To get started you need Poetry's bin directory ($HOME/.poetry/bin) in your `PATH`
environment variable. Next time you log in this will be done
automatically.

To configure your current shell run `source $HOME/.poetry/env`

$ curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python3 - --uninstall
# We are sorry to see you go!

This will uninstall Poetry.

It will remove the `poetry` command from Poetry's bin directory, located at:

$HOME/.poetry/bin

This will also remove Poetry from your system's PATH.

$ curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python3

I have to test again.
