# Bug report ### Bug description: Context: In Python 3.12 the function importlib.resources.files() was updated: https://docs.python.org/3/library/importlib.resources.html#importlib.resources.files > Changed in version 3.12: package parameter was renamed to anchor. anchor can now be a non-package module and if omitted will default to the caller’s module. package is still accepted for compatibility but will raise a [DeprecationWarning](https://docs.python.org/3/library/exceptions.html#DeprecationWarning). Consider passing the anchor positionally or using importlib_resources >= 5.10 for a compatible interface on older Pythons. The Issue: When using `importlib.resources.files()`, I am able to open and read a text file included as package data in my package. However, if I zip up my package with zipapp and run the .pyz file, it is unable to read the text file. If I use `importlib.resources.files("mypkg")` it will work in both cases. Minimal example: Create a project directory named `mypkg` with the [src layout](https://setuptools.pypa.io/en/latest/userguide/package_discovery.html#src-layout). Create the following files. mypkg/src/mypkg/a.py ```python import importlib.resources def main(): x = importlib.resources.files() / "data.txt" print(x.read_text()) ``` mypkg/src/mypkg/data.txt ```text datadata ``` In pyproject.toml make sure to set up the entry script and include the data file. mypkg/pyproject.toml ``` [project.scripts] myscript = "mypkg.a:main" [tool.setuptools.package-data] mypkg = ["*.txt"] ``` Install the package into a fresh Python (virtual) environment with pip. Run `myscript` and verify it prints `datadata`. Now back in the mypkg project root folder, we will generate a .pyz file with zipapp and run the program from the .pyz file. Run `pip install . --target buildtemp --upgrade && python3 -m zipapp buildtemp --main mypkg.a:main -p '/usr/bin/env python3' -o mypkg.pyz` in the terminal. Run `./mypkg.pyz`. This results in an error: ``` Traceback (most recent call last): File "<frozen runpy>", line 198, in _run_module_as_main File "<frozen runpy>", line 88, in _run_code File "/home/win/code/sandbox/python/mypkg/./mypkg.pyz/__main__.py", line 3, in <module> File "/home/win/code/sandbox/python/mypkg/./mypkg.pyz/mypkg/a.py", line 6, in main File "/home/win/.local/share/mise/installs/python/3.12.4/lib/python3.12/importlib/resources/abc.py", line 89, in read_text with self.open(encoding=encoding) as strm: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/win/.local/share/mise/installs/python/3.12.4/lib/python3.12/importlib/resources/_adapters.py", line 139, in open raise FileNotFoundError("Can't open orphan path") FileNotFoundError: Can't open orphan path ``` Note that if you change `x = importlib.resources.files() / "data.txt"` to `x = importlib.resources.files("mypkg") / "data.txt"`, it will work when running the .pyz file. ### CPython versions tested on: 3.12 ### Operating systems tested on: Linux, macOS <!-- gh-linked-prs --> ### Linked PRs * gh-123037 * gh-123986 * gh-124011 <!-- /gh-linked-prs -->
