- Exact error message and exit code:
  - error: subprocess-exited-with-error
  - Preparing editable metadata (pyproject.toml) did not run successfully.
  - exit code: 1
  - meson-python: error: Could not find the specified meson: "vendored-meson/meson/meson.py"
  - error: metadata-generation-failed
  - Note: This error originates from a subprocess, and is likely not a problem with pip.

- Failing command/step:
  - Step: 7/7 RUN python -m pip install -e . --no-build-isolation
  - Command exit: 1

- Missing packages or files mentioned:
  - vendored-meson/meson/meson.py (required by meson-python)

- Version mismatch information:
  - Base image uses python:3.12-slim-bullseye.
  - The apt install during build pulls in many Python 3.9 packages (python3.9, python3-venv, python3-dev, etc.), indicating multiple Python minor versions present in the environment, but no explicit mismatch error is shown in the log. The failure occurs in NumPy packaging while attempting an editable install.

Failing step
- Dockerfile step: RUN python3 -m pip install --no-cache-dir meson ninja cython mesonpy

Exact error messages (preserved)
- "ERROR: Could not find a version that satisfies the requirement mesonpy (from versions: none)"
- "ERROR: No matching distribution found for mesonpy"

Exit code
- The overall build failure ends with exit code 1 (as shown by the Docker build error chain).

Missing packages or files mentioned
- mesonpy is missing/not distributable in this environment: no matching distribution found for mesonpy.

Version mismatch / environment notes
- Base image used: python:3.12-slim
- No explicit version mismatch shown in the error; the failure indicates that mesonpy has no compatible distribution available for this environment (likely related to Python 3.12 compatibility on PyPI). The log does not show other package-version conflicts.

Dockerfile reference
- Failing line: Dockerfile:18
- Context: The install command attempts to install meson, ninja, cython, and mesonpy but only mesonpy is reported as unavailable.

- Exact error messages and exit code:
  - "ERROR: Could not find a version that satisfies the requirement mesonpy (from versions: none)"
  - "ERROR: No matching distribution found for mesonpy"
  - The build failed with exit code: 1

- Missing packages/files mentioned:
  - mesonpy could not be found on PyPI for this environment; “from versions: none” and “No matching distribution found for mesonpy”

- Version mismatch / related context:
  - Base image is python:3.11-slim, but the build sequence later shows apt installations pulling Python 3.13 packages (e.g., libpython3.13-minimal, python3.13-minimal, python3-13, etc.), indicating a Python version mismatch between the base image (3.11) and the installed Python 3.13 stack during apt-based setup. This may affect compatibility with mesonpy.

- Note: Earlier steps completed (e.g., pip tooling setup), but the failure occurs specifically at the mesonpy installation.

  - ERROR: No matching distribution found for mesonpy

- Failing command/step:
  - [ 4/10] RUN python3 -m pip install --no-cache-dir meson ninja cython mesonpy

- Missing packages or files mentioned:
  - mesonpy (not found on PyPI for this environment)

- Version mismatch / contextual notes:
  - Base image uses python:3.10-slim, but the build later shows system Python 3.13 components being installed (e.g., libpython3.13-*, python3.13-*, etc.), indicating a Python version mismatch between the interpreter used by /usr/local (3.10) and the system Python 3.13 packages.
  - This mismatch may contribute to mesonpy having no compatible distribution available for the current interpreter/platform.

  - Later apt steps install Python 3.13 components (e.g., libpython3.13, python3.13), indicating a mixed Python environment. The mismatch may contribute to the vendored Meson not being found.

- Failing/missing file or package:
  - vendored-meson/meson/meson.py under /app (content appears as a 404 Not Found response, indicating the vendored Meson script could not be loaded correctly)

- Version/mismatch information:

  - meson-python version installed around the failing step: 0.19.0
  - build package version installed earlier: 1.4.0
  - The error occurs during building sdist with meson-python, suggesting a problem with the vendored Meson distribution.
