Fails if any dependencies are VCS dependencies

[Fuyukai]

Example pyproject:

$ cat pyproject.toml
[tool.poetry]
name = "test"
version = "0.1.0"
description = ""
authors = [""]
readme = "README.rst"
packages = [{include = "test", from = "src"}]

[tool.poetry.dependencies]
python = "^3.11"
httpx = {git = "https://github.com/encode/httpx.git"}


[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

Tool output:

$ poetry relax
Checking dependencies in group 'main' for relaxable constraints...

Could not parse version constraint:

Thanks for the issue! The next step is to reproduce this in the test suite and get a full traceback. Presumably we can just skip any complex version specifications but maybe there are some cases where a mapping is used that we should support.

Thanks for getting this fixed so quickly!
