• 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: cygwin
• Poetry version: Poetry version 1.1.8
• Link of a Gist with the contents of your pyproject.toml file:

[tool.poetry]
name = "xxx"
version = "0.2"
description = ""
authors = ["xxx"]

[tool.poetry.scripts]
xxx-yyy = "xxx:yyy"
xxx-zzz = "xxx:zzz"

Issue

when running poetry install in the repo, the script produced is :

#!/.../bin/python
from xxx import yyy

if __name__ == '__main__':
    yyy()

(from

but when running pip install ., the script produced is :

#!/.../python
# -*- coding: utf-8 -*-
import re
import sys
from xxx import yyy
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(yyy())

I believe pip is the correct behaviour with the sys.exit :)
