Poetry is impossible to install on the python docker images.

• 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).

Issue

Poetry will not install on the docker images.

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

This gives the “module not found” error with “cleo” as the missing module, same as #3345.

If I try the workaround in that issue-

install_url="https://raw.githubusercontent.com/python-poetry/poetry/master/install-poetry.py"
curl -sSL "$install_url" | POETRY_HOME=$install_path python3 - --git "https://github.com/python-poetry/poetry.git@master"

I just get more errors-

app_1  | The canonical source for Poetry's installation script is now https://install.python-poetry.org. Please update your usage to reflect this.

It seems like the installer is ignoring the git branch that is passed to it.

I’ve tried this with the python3.9 and python 3.10 containers.

Created a request on Docker Hub to create poetry-based images, please support!

Docker context is different to shell context, you need to use ENV and WORKDIR:

FROM python:3.10
RUN set -xe
RUN curl -sSL https://install.python-poetry.org | python3 - --git https://github.com/python-poetry/poetry.git@master
ENV PATH="/root/.local/bin:$PATH"
RUN poetry --version
RUN poetry new foobar
WORKDIR foobar
RUN poetry add pycowsay
RUN poetry run pycowsay 'Hello world!'
