Environment Versions

1. OS Type: macOS
2. Python version: Python 3.8.0
3. pip version: pip 20.2.2
4. pip-tools version: pip-compile, version 5.5.0

Steps to replicate

1. Create a folder:

$ mkdir -p foo/bar

2. Create setup.py:

$ cat << EOF > foo/bar/setup.py
from setuptools import setup
setup(name="bar", version="0.1", install_requires=["six"])
EOF

3. Run pip-compile:

$ pip-compile foo/bar/setup.py
#
# This file is autogenerated by pip-compile
# To update, run:
#
#    pip-compile foo/bar/setup.py
#
six==1.15.0
    # via bar (foo/bar/setup.py)

Expected result

$ ls foo/bar
setup.py  requirements.txt

Actual result

$ ls foo/bar
setup.py  setup.txt

Hi @atugushev
Can I work on this issue?

[atugushev]

@peymanslh sure! Feel free to.

This also happens to be fixed by the current state of #1329, though the annotations specify (setup.py) rather than (foo/bar/setup.py), since the files are adjacent.
