pip 19.1 breaks Poetry #1049
Description
- 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 (
-vvvoption).
- OS version and name: OSX 10.13
- Poetry version: 0.12.2

Issue
After upgrading pip to version 19.1 (relased 5 hours ago), I can't install my projects using poetry anymore:
abilian-core ❯ poetry install
Installing dependencies from lock file
Nothing to install or update
- Installing abilian-core (0.11.0-dev)
A setup.py file already exists. Using it.
[EnvCommandError]
Command ['/Users/fermigier/.virtualenvs/abilian-core/bin/pip', 'install', '-e', '/Users/fermigier/projects/abilian-core',
'--no-deps'] errored with the following output:
Obtaining file:///Users/fermigier/projects/abilian-core
ERROR: Error installing 'file:///Users/fermigier/projects/abilian-core': editable mode is not supported for pyproject.toml-style projects. This project is being processed as pyproject.toml-style because it has a pyproject.toml file with a "build-backend" key in the "build_system" value. See PEP 517 for the relevant specification.
install [--no-dev] [--dry-run] [-E|--extras EXTRAS] [--develop DEVELOP]
(Downgrading pip to 19.0.3 restores the usual behavior).
Not sure if it's a pip or a poetry issue, but I'm posting it here so that poetry users are aware of the issue.
