Issue

The issue is that when determining the install-requires dependency, it analyzes the setup.py file and notices that there is a install-requires but cannot parse it (it's a list comprehension and not a list). The end result is that this is then silently ignored here: https://github.com/python-poetry/poetry/blob/master/src/poetry/inspection/info.py#L565 because it doesn't check if install-requires is filled (and in fairness, shouldn't since some packages don't have that).

The crux of the issue is basically that in the SetupReader, there is no distinction between "value absent" and "value can't be read".

The proper behavior is probably to fallback to building the package if allowed in the case when the field exists but can't be extracted.

Steps to reproduce:

poetry new poetry-demo
cd poetry-demo
poetry add "git+https://github.com/openai/CLIP.git"

If you look at the CLIP project, you will see it has some requirements like torch but the poetry lock file lists no such thing and looks like this:

[[package]]
name = "clip"
version = "1.0"
description = ""
optional = false
python-versions = "*"
files = []
develop = false

[package.extras]
dev = ["pytest"]

[package.source]
type = "git"
url = "https://github.com/openai/CLIP.git"
reference = "HEAD"
resolved_reference = "a1d071733d7111c9c014f024669f959182114e33"
