ModuleNotFoundError: No module named 'platformdirs' when doing poetry install --dev

[stianlagstad]

• 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: python:3.9.6-buster

• Poetry version: 1.1.8

• Link of a Gist with the contents of your pyproject.toml file: Repo with issue reproduced: https://github.com/stianlagstad/reproduce-poetry-virtualenv-issue

Issue

First running poetry install --no-dev and then running poetry install leads to the error ModuleNotFoundError: No module named 'platformdirs'. I've setup a repository that reproduces the issue: https://github.com/stianlagstad/reproduce-poetry-virtualenv-issue.

Dockerfile:

FROM python:3.9.6-buster

COPY pyproject.toml .
COPY poetry.lock .

RUN pip list
RUN pip install poetry
RUN pip list
RUN pip show poetry

# As we're inside a docker container, we want to install globally
RUN poetry config virtualenvs.create false

RUN poetry install --no-dev

# RUN pip install virtualenv  # Adding this makes the error go away

# Error `ModuleNotFoundError: No module named 'platformdirs'` happens here:
RUN poetry install -vvv

Our actual Dockerfile is using multi stage builds, and in our final image (our testrunner) we want the dev dependencies installed. That's why we first do poetry install, and then later to poetry install --dev.

Error output:

$ docker build -t test . --no-cache

Am I doing anything wrong? Is this expected?

[finswimmer]

Hello @stianlagstad,

there are multiple reasons for this:

First, never install poetry into the environment that should be managed by poetry. There's a good chance that otherwise dependencies needed by poetry itself gets removed or updated/downgrade when installing a project by poetry. Instead use the official installer or pipx.

Second, at the moment poetry removes dev-dependencies (and the dependecies of these dependencies) it finds some in the current environment, when running poetry install --no-dev. In your case it finds platformdirs and removes it. Because that's a dependency of poetry itself, poetry is unusable afterwards. With the upcoming minor release (1.2.0) this behaviour changes: Any locked packages will be kept in the environment regardless of what is asked via the install command unless the --sync option is specified..

So here is my recommendation:

• Use the official installer or pipx to install poetry in it's isolated environment
• Rethink whether you really want to use virtualenvs.create false. venvs within a docker container are absolutely valid, because they isolate the package environment from the os environment (your docker container!) to avoid conflicts.

Thanks for explaining (and for the fast answer), @finswimmer !

[blueyed]

Note that with poetry 1.1.9 (due to #4507 likely) the behavior when installing poetry in its own virtualenv (or via pipx) changed the location where packages are being installed (into /opt/poetry/lib/python3.9/site-packages, instead of /usr/local/lib/python3.9/site-packages/ (from the system Python)).
