Downgrade poetry version

Question

I need to downgrade my version of poetry to version 1.2.1.

Currently, it's 1.2.2.

>>> poetry --version
Poetry (version 1.2.2)

I use the following command:

>>> curl -sSL https://install.python-poetry.org | POETRY_VERSION=1.2.1 python3 -
Retrieving Poetry metadata

The latest version (1.2.1) is already installed.

But I'm told that 1.2.1 is already installed. Yet the poetry version is still stuck on the original.

>>> poetry --version
Poetry (version 1.2.2)

The answer given here doesn't work (poetry self update@1.2.1) => The command "self" does not exist.

What am I doing wrong here?

What's the output of `which -a poetry`. I guess you have multiple installs of Poetry on your system. — finswimmer, Dec 20 '22 at 10:24
have you tried to uninstall v1.2.2 before installing v1.2.1? — Emil Haas, Jan 12 '23 at 15:51

One can downgrade (or upgrade) poetry through poetry self update command.

So, you can downgrade to 1.2.1 by running:

poetry self update 1.2.1

This is only true, if you have installed Poetry via `pip`. This is explicit not recommended. Always install Poetry in it own isolated environment. Please refer to the [install instructions](https://python-poetry.org/docs/#installation) for more details. – finswimmer Dec 20 '22 at 10:27

I made sure to run terminal as administrator I then install poetry 1.2.2 with the command

pip install poetry=="1.2.2"

it installed successfully, then installed the "1.2.1" version with:

pip install poetry=="1.2.1"

The new install with a lower version automatically removed the version="1.2.2".

after you install what you need, i recommend you restart your terminal before running anything python. Maybe that will help.

if the above does not work, uninstall all poetry related packages then reinstall the 1.2.1 version.

If you need to manage multiple versions of poetry, then the poetry developers recommend pipx.

A bit ironic, since poetry's job is managing software versions. Quis custodiet ipsos custodes?
