Setting credentials through env. variable are not working

Issue

I’m failing to use env. variables to set custom pypi credentials.

My pyproject.toml contains private pypi’s like this:

[[tool.poetry.source]]
url = "https://XXXXX/nexus/repository/pypi-central/simple"
name = "nexus"

I’m running this script:

export POETRY_HTTP_BASIC_NEXUS_USERNAME=****
export POETRY_HTTP_BASIC_NEXUS_PASSWORD=****
poetry install

and it fails with:

[EnvCommandError]
Command ['/opt/.cache/pypoetry/virtualenvs/YYYY-4zvP7SOo-py3.8/bin/pip', 'install', '--no-deps', '--index-url', 'https://XXXXX/nexus/repository/pypi-central/simple', '--extra-index-url', 'https://pypi.org/', 'six==1.12.0'] errored with the following return code 2, and output:

I investigated the code and it seems that credentials are never acquired separately from config, but always as a pair. That means that code never ask for http-basic.nexus.password and http-basic.nexus.username, but for http-basic.nexus then the value is used as a dict (search for password_manager.get_http_auth usage). I could not find single test case, so I wrote one, fill free to use it:

This isn’t working on the most recent release, 1.0.8.

I got the same error, but it was not related to the used python version. My mistake in a CI environment was exporting the environment variables POETRY_HTTP_BASIC_XXX_USERNAME + POETRY_HTTP_BASIC_XXX_PASSWORD and executing all the poetry config commands in one step and the poetry install in another where the env variables were not present anymore.

TLDR:

• set the environment variable right before usage of poetry install. Setting it before the poetry config commands you may execute does not persist them for later executions of poetry install.
