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:

I had a similar issue today. I spent a good part of my evening looking at poetry's source code. It seems, based on poetry's pyproject.toml, that poetry runs on anything python v2.7 thru v3.6.
Have you worked on your issue using, perhaps v3.6 or below?

[nierob]

Nope, I was trying on python 3.7.5 and some 3.8, I think :(

Thanks!

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.
