Specifying private repository URL via environment variable not possible

• 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: Debian GNU/Linux 10 (buster)

• Poetry version: 1.1.8

Issue

Specifying the URL of a private repository via an environment variable does not result in a working configuration. For instance after export POETRY_REPOSITORIES_MYREPO=https://my-repo-url/ running poetry add some_package results in

  AttributeError

  'str' object has no attribute 'get'

  at ~/.poetry/lib/poetry/installation/authenticator.py:151 in _get_credentials_for_netloc_from_config

      148│             if not repository_config:
      149│                 continue
      150│
    → 151│             url = repository_config.get("url")
      152│             if not url:
      153│                 continue
      154│
      155│             parsed_url = urlparse.urlsplit(url)

In contrast, it works without issues when specifying the URL via poetry config, such as poetry config --local repositories.myrepo https://my-repo-url/ Meaning the repository is accessed without exceptions doing e.g. poetry add some_package.

I have tracked down the cause to this code https://github.com/python-poetry/poetry/blob/master/src/poetry/config/config.py#L113-L126

It seems that the code that invokes Config.get() expects a dictionary such as {url : "https://my-repo-url/"} to be returned when Config.get() is called with repositories.myrepo as argument. And that is what happens in the lower portion of Config.get. That code is reached only when the env variable is not set though.

When the env variable is set, the upper portion is used, which always returns a string ('https://my-repo-url/' in this case), leading to the exception.

This doesn’t reproduce for me on 1.2.x. @vergenzt and @tilsche are interested in something different – either #5958 or #1632.
