--extra-index flag throws error

[matteosantama]

My CI starts to fail if I bump nox-poetry from 0.8.1 to 0.8.2 with the following error

...
 File "/usr/local/lib/python3.8/site-packages/nox_poetry/sessions.py", line 209, in export_requirements
    constraints = to_constraints(self.poetry.export())
  File "/usr/local/lib/python3.8/site-packages/nox_poetry/sessions.py", line 88, in to_constraints
    return "\n".join(_to_constraints())
  File "/usr/local/lib/python3.8/site-packages/nox_poetry/sessions.py", line 84, in _to_constraints
    constraint = to_constraint(requirement, line)
  File "/usr/local/lib/python3.8/site-packages/nox_poetry/sessions.py", line 69, in to_constraint
    raise RuntimeError(f"line {line}: {requirement_string!r}: {error}")
RuntimeError: line 1: '--extra-index-url https://gitlab.com/api/v4/projects/20895990/packages/pypi/simple':

Thanks for reporting!

We should ignore requirement lines starting with ˋ-ˋ as it is not a valid way to start a package name, and must be a pip option. The function is ˋto_constraintˋ in the sessions module of you're interested in submitting a PR.

@matteosantama A fix was released in 0.8.3, can you try?

Thanks @cjolowicz your patch sloved part of my error I get since updating from 8.1 to 8.2.

I think this is related to the extra url I am setting:

[[tool.poetry.source]]
name = "default"
url = "{{cookiecutter.pip_index_url}}"
secondary = false

Here is a log

@cjolowicz Unfortunately the patch doesn't totally resolve the issue. I am getting the same error as @RomainBrault

My pyproject.toml looks like

[[tool.poetry.source]]
name = "gitlab_pypi"
url = "https://gitlab.com/api/v4/projects/XXX/packages/pypi/simple"
secondary = false

@matteosantama @RomainBrault thanks for the input and the PR!

Another fix was released in 0.8.4, please let me know if you still encounter any problems.
