How to find which pip package owns a file?

Question

I have a file that I suspect was installed by pip. How can I find which package installed that file?

In other words, I'm looking for a command similar to pacman -Qo filename or dpkg -S filename, but for pip. Does it exist? Or should I use some combination of pip and grep? In that case, I don't know how to list all the file installed.

Answer 1

You could try with

pip list | tail -n +3 | cut -d" " -f1 | xargs pip show -f | grep "filename"

Then search through the results looking for that file.

Answer 2

You can use a python script like this:

#!/usr/bin/env python

import sys
try:
    from pip.utils import get_installed_distributions
except ModuleNotFoundError:
    from pip._internal.utils.misc import get_installed_distributions

MYPATH=sys.argv[1]
for dist in get_installed_distributions():
    # RECORDs should be part of .dist-info metadatas
    if dist.has_metadata('RECORD'):
        lines = dist.get_metadata_lines('RECORD')
        paths = [l.split(',')[0] for l in lines]
    # Otherwise use pip's log for .egg-info's
    elif dist.has_metadata('installed-files.txt'):
        paths = dist.get_metadata_lines('installed-files.txt')
    else:
        paths = []

    if MYPATH in paths:
        print(dist.project_name)

Usage looks like this:

$ python lookup_file.py requests/__init__.py 
requests

I wrote a more complete version here, with absolute paths:
