poetry self update not updating poetry (new version available) properly. poetry --version showing old version

• I am on the latest Poetry version.

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

• Poetry version: 1.1.9

Issue

When poetry self update is ran, it doesn’t update poetry properly. It is showing old version for command poetry --version instead of showing new version

Minimal steps to reproduce

1. Run new docker python image docker run -it python bash
2. Install poetry curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python -
3. export PATH="/root/.local/bin:$PATH"
4. poetry --version Poetry version 1.1.9
5. Run self update to preview poetry self update --preview
6. Rerun poetry --version It shows Poetry version 1.1.9 instead of preview version

This issue is also present when updating poetry from 1.1.8 to 1.1.9. Other version not tested

Full steps

$ docker run -it python bash
root@aeac3f8b58ef:/# curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python -
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:

/root/.local/bin

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

Installing Poetry (1.1.9): Done

Poetry (1.1.9) is installed now. Great!

To get started you need Poetry's bin directory (/root/.local/bin) in your `PATH`
environment variable.

Add `export PATH="/root/.local/bin:$PATH"` to your shell configuration file.

Alternatively, you can call Poetry explicitly with `/root/.local/bin/poetry`.

You can test that everything is set up by executing:

`poetry --version`

root@aeac3f8b58ef:/# export PATH="/root/.local/bin:$PATH"
root@aeac3f8b58ef:/# poetry --version
Poetry version 1.1.9
root@aeac3f8b58ef:/# poetry self update --preview

It happened again after running poetry self update from Poetry 1.1.9. It says it updated Poetry to 1.1.10, but poetry --version returns 1.0.9.

Running the install script again fixes the issue, installing Poetry 1.1.10.

curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py | python -

On 1.1.9, poetry self update also throws a RuntimeError “Poetry was not installed with the recommended installer. Cannot update automatically.” even though I have used the recommended installer. Just to be sure, I uninstalled poetry and then reinstalled with the new installer, and I’m still getting the error.

Here’s the full traceback:

RuntimeError
