maturin failed: No such file or directory (os error 2)

Bug Description

Running python -m build for my project fails with maturin 0.14.1 and the new src project structure.

Your Python version (python -V)

Python 3.11.0

Your pip version (pip -V)

pip 22.3.1 from /home/lily/.virtualenvs/kolo/lib/python3.11/site-packages/pip (python 3.11)

What bindings you're using

pyo3

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

Create a mixed rust/python project using the new python src layout introduced in maturin 0.14.

Run python -m build:

$ python -m build
* Creating venv isolated environment...
* Installing packages in isolated environment... (maturin>=0.14,<0.15)
* Getting build dependencies for sdist...
* Building sdist...
Running `maturin pep517 write-sdist --sdist-directory /home/lily/work/klopp/kolo/python/dist`
💥 maturin failed
  Caused by: No such file or directory (os error 2)
Error: command ['maturin', 'pep517', 'write-sdist', '--sdist-directory', '/home/lily/work/klopp/kolo/python/dist'] returned non-zero exit status 1

ERROR Backend subprocess exited when trying to invoke build_sdist

Or run maturin directly:

$ maturin pep517 write-sdist --sdist-directory ~/work/klopp/kolo/python/dist/
💥 maturin failed
  Caused by: No such file or directory (os error 2)

maturin develop runs with no errors:
