Incomplete installation of libraries from git

[bheemaguli]

I have a remote git repository dependency and have been installing as pip install -e git+https://repo@commithash#egg=foorepo and the locally installed package had all files similar to the remote repo.

├── repo
│   ├── foorepo
│          │── subfolder
│          │    │─ file.py
│          │── setup.py

At the end of installatio, I was able to import function from file.py as from foorepo.subfolder.file import function

But in uv, the equivalent installs like uv add --editable "git+https://repo@commithash" or uv pip install "git+https://repo@commithash" are cloning the repo but the subdirectories seems to be missing

├── repo
│   ├── foorepo
│          │── setup.py

and importing is raising ModuleNotFoundError: No module named 'foorepo'

I assumed the issue to be similar to https://github.com/astral-sh/uv/issues/1708 but none of the solutions discussed there seem to be working. Document has not been helpful in this regards.

Any idea on what the issue might be. I have tested on current (0.4.7) and few older versions of uv and issue is same across all.

I have found the issue. In the remote repo, the setup file to build the package has code as

setup(
    name="repo",
    version=repo.__version__,
    packages=["foorepo"],
    include_package_data=True,
    license="MIT",
    ...
 )

but uv's implementation of build or maybe setuptools is not able to recognise packages=["foorepo"] The issue can be fixed by

from setuptools import setup, find_packages

setup(
    name="repo",
    version=repo.__version__,
    packages=find_packages(),
    include_package_data=True,
    license="MIT",
    ...
 )

Will keep this issue open to see if this is actual issue.

i'm having the same issue. the project i'm trying to install from uses no setup.py, only a pyproject.toml containing some irrelevant stuff and

[tool.setuptools]
packages = ["project_module"]

i guess something more is needed? i'm porting from pipenv and it previously worked fine with just this minimal declaration.

Unfortunately I probably won't be able to help here unless there's a reproduction that I can use.

[notarealuseralcemy]

okay, thanks! i'll create an mre next week

[charliermarsh]

Awesome thank you!

or... now.

mkdir new_project && cd new_project
uv init
uv add "git+https://github.com/notarealuseralcemy/uv-package-mre.git"
ls .venv/lib/python*/site-packages/some_module
# > __init__.py main.py
ls ../uv-package-mre/example_module  # or see https://github.com/notarealuseralcemy/uv-package-mre/example_module
__init__.py     main.py         some_nested_module

contents of uv-package-mre/pyproject.toml:

[project]
name = "uv-package-mre"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.11"
dependencies = []

[tool.setuptools]
packages = ["some_module"]

so you can see that some_nested_module is being omitted from the install. this isn't my forte so i dunno if i'm doing something totally wrong, but as i said, there doesn't seem to be this issue with pipenv and the same setup.

[notarealuseralcemy]

actually i think this issue is just caused by my misunderstanding of how the packages declaration works for setuptools, in fact it's not recursive, and each submodule should be declared explicitly? so here it should be

packages = ["some_module", "some_module.some_nested_module"]

but i'm not sure.

i also tried

[tool.setuptools.packages.find]
where = ["some_module"]

which is explicitly stated here to include submodules, but that also doesn't work.

i could eventually get it to work by adding a glob operator like:

[tool.setuptools.packages.find]
where = ["some_module*"]

but i don't think this should be required according to the setuptools docs, so i think it is an issue with uv?

@notarealuseralcemy I saw that python -m build also excludes the files in the same way, so that confirms it is not /just/ an uv issue if it was a bug. I.e the "missing" files can be reproduced without involving uv.
