pip wheel --find-links --no-index fails if package has pyproject.toml

[asottile]

Environment

• pip version: 10.0.1
• Python version: 3.6.5
• OS: macos (also ubuntu bionic)

Description

pip wheel --no-index --find-links file:///... cannot build a wheel if a project contains a pyproject.toml file.

Expected behavior

It should be able to, I suspect this is related to the PEP518 work, though in this specific case there are no PEP518 specifiers in this pyproject.toml.

How to Reproduce

pip download --no-deps --no-binary :all: aiohttp==2.3.1
pip wheel --no-deps --no-index --find-links "file://$PWD" aiohttp 2.3.1

Output

$ pip wheel aiohttp==2.3.1 --find-links file://$PWD --no-index --no-deps
Looking in links: file:///private/tmp/t
Collecting aiohttp==2.3.1
  Could not find a version that satisfies the requirement setuptools (from versions: )
No matching distribution found for setuptools

Here are the contents of the pyproject.toml at v2.3.1

My workaround for now is to remove --no-index, though ideally I want that assertion.

You can disable build isolation with --no-build-isolation.

Indeed. The rest of this issue basically #5416.

This is an exact duplicate of #5402
