Cannot configure options through environment variables

[jpreese]

• 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: macOS Montery version 12.4
• Poetry version: 1.2.0b2

Issue

When calling poetry using environment variables to configure options, they do not seem to be respected. From the documentation, I would expect to be able to create a virtual environment without pip using something like the following:

POETRY_VIRTUALENVS_OPTIONS_NO_PIP=true POETRY_VIRTUALENVS_IN_PROJECT=true POETRY_VIRTUALENVS_PATH=.venv poetry install

The last two values work. Poetry is installed in the project in a folder named .venv -- however, pip is still in the site-packages folder.

I've tried the other "options" as well, and tried different ways to name them but have not been successful.

Are options able to be configured by environment variables?

Looks like not - see

poetry/src/poetry/utils/env.py

Line 983 in 8b64088

flags=self._poetry.config.get("virtualenvs.options"),

that'll cause poetry to look for the POETRY_VIRTUALENVS_OPTIONS environment variable - which doesn't help at all

still no way to make --always-copy work for virtualenv creation?

[dimbleby]

this issue is about not being able to configure those options through environment variables, per #7873 (comment) it works fine when configured another way

I was hit by this today. POETRY_VIRTUALENVS_OPTIONS_NO_PIP=true seems to have no effect.

This is the end result of my venv after poetry install.

Using Poetry version 1.7.1 (on Windows 10) noticed same issue with POETRY_VIRTUALENVS_OPTIONS_SYSTEM_SITE_PACKAGES.

Setting it to true will show correctly in the config list:
virtualenvs.options.system-site-packages = true

But when creating the venv (poetry install) or running poetry env use <python>
The line in pyvenv.cfg is not set correctly:
include-system-site-packages = false

If using command poetry config --local virtualenvs.options.system-site-packages true
the project's poetry.toml is updated correctly and also pyvenv.cfg has correct setting in venv.

Using Poetry version 1.7.1 on Ubuntu (WSL2) and I can also reproduce this error. I did notice, however, that some flags work. For example, POETRY_VIRTUALENVS_IN_PROJECT=true resulted in the .venv being created in the project's root.

folks, this all has been well understood since #5906 (comment). No need to keep reporting that it is still a thing - that's represented already by this still being open.

what this issue needs now is someone who cares enough to make a merge request fixing it: if that's you then please go ahead!

Fixed at #9015
