• 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 (-vvv option).

• OS version and name: macOS 10.15.4
• Poetry version: 1.0.5

Issue

I had a dummy setup.py (based on this post):

#!/usr/bin/env python

import setuptools

if __name__ == "__main__":
    setuptools.setup()

When that file is present two things happen when doing poetry install:

• egg info is now created under UNKNOWN.egg-info
• entry_points.txt is no longer generated

Interestingly enough entry_points.txt is still present in a generated wheel.

Steps to reproduce

poetry new testpoint
cd testpoint
printf '\n[tool.poetry.plugins.test]\nmain = "foo"' >> pyproject.toml
echo 'import setuptools; setuptools.setup()' > setup.py
poetry install
