- Failing step/command:
  - [builder 6/6] RUN python3 -m pip wheel . -w /wheel

- Exact error message and exit code:
  - error: metadata-generation-failed
  - exit code: 1
  - Note: The inner cause shown in the log is:
    - meson-python: error: The package requires Python version >=3.11, running on 3.10.12

- What happened:
  - Building a wheel from source (pandas) failed during metadata generation for the package at /pandas-src.

- Missing packages or files:
  - None explicitly missing; the failure is due to a Python version mismatch.

- Version mismatch info:
  - The environment uses Python 3.10.12 (Run-time dependency python found: YES 3.10) while the package (via Meson/Ninja) requires Python >= 3.11.
  - Base image shown: python:3.12-slim, but the installed/run-time Python is 3.10.12.
  - Specific message: "meson-python: error: The package requires Python version >=3.11, running on 3.10.12"

Summary (under 1500 chars):

- Failing step: [builder 7/7] RUN python -m pip wheel . -w /wheelhouse --no-cache-dir
- Exact error and exit code:
  - Error: ERROR: Directory '.' is not installable. Neither 'setup.py' nor 'pyproject.toml' found.
  - Exit code: 1
- Why it failed:
  - The wheel command is run from the current directory (.), which lacks packaging metadata. There is no setup.py or pyproject.toml in the /src/pandas context being wheel-ed, so pip cannot build a wheel.
- Missing packages/files referenced:
  - setup.py or pyproject.toml is missing in the directory being wheel-ed.
- Version/mismatch details:
  - Builder image uses python:3.12-bullseye; runtime image uses python:3.12-slim-bullseye, indicating a base-image version mismatch between builder and runtime. Both are Debian bullseye variants, but the non-slim vs slim base differs.

- Missing packages or files mentioned
  - None indicated. The failure is due to a malformed here-document in the RUN command, not a missing package/file.

- Version mismatch info
  - No explicit version mismatch error reported. Base image is python:3.12-bullseye; the error stems from shell heredoc syntax, not a version issue.

  - None mentioned as missing; error is due to a shell here-document syntax issue during the here-doc.

- Version mismatch info
  - Base image shown: python:3.12-bullseye
  - A pandas wheel was built with an unknown version: pandas-0+unknown-cp312-cp312-linux_x86_64.whl, indicating a version/config issue for pandas in this build.

Summary of Docker build error

- Exact error message and exit code
  - ERROR: failed to build: failed to solve: process "/bin/sh -c bash -lc 'cat > /smoke.py << \"PY\"\\n#!/usr/bin/env python3\\nimport pandas as pd\\nimport numpy as np\\nprint(\"pandas-version:\", pd.__version__)\\nprint(\"numpy-version:\", np.__version__)\\nPY'" did not complete successfully: exit code: 2
  - Inline diagnostics shown:
    - bash: line 1: warning: here-document at line 1 delimited by end-of-file (wanted `PYn#!/usr/bin/env')
    - bash: -c: line 1: syntax error near unexpected token `('

- Failing command/step
  - [builder 8/8] RUN bash -lc 'cat > /smoke.py << "PY"\n#!/usr/bin/env python3\nimport pandas as pd\nimport numpy as np\nprint("pandas-version:", pd.__version__)\nprint("numpy-version:", np.__version__)\nPY'
  - The failure occurs while attempting to create /smoke.py with a here-document.

- Missing packages or files mentioned
  - None explicitly mentioned as missing. The log shows a syntax/here-doc error, not a missing package/file issue.

- Version mismatch info
  - None reported. The image used is python:3.12-bullseye, but the error is due to shell here-document syntax, not a version mismatch. Earlier steps install Python 3.9 components during apt-get, but no version mismatch is stated as cause.
