Maturin failed to find python interpreter

[ritchie46]

When setting manylinux=auto or (lower than 2_24), the pipeline fails as it cannot find a python interpreter.

This is the yaml snippet:

  build_manylinux:
    name: Create Release manylinux
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Prepare maturin publish
        shell: bash
        run: |
          rm py-polars/README.md
          cp README.md py-polars/README.md

      - uses: actions/setup-python@v2
        with:
          python-version: 3.7
          architecture: x64

      - name: publish x64_64
        uses: messense/maturin-action@v1
        env:
          MATURIN_PASSWORD: ${{ secrets.PYPI_PASS }}
          RUSTFLAGS: '-C target-feature=+fxsr,+sse,+sse2,+sse3,+ssse3,+sse4.1,+sse4.2,+popcnt,+avx,+fma'
        with:
          rust-toolchain: nightly-2022-08-22
          maturin-version: '0.13.0'
          command: publish
          args: -m py-polars/Cargo.toml --skip-existing -o wheels -i python -u ritchie46

This is the error in question:

That's odd, can you try maturin 0.13.2?

[messense]

Also can you try remove -i python? abi3 wheel does not need it, it might have confused maturin in manylinux2014 container because there isn't any python executable in PATH python is Python 2.7 in manylinux2014 docker container

args: -m py-polars/Cargo.toml --skip-existing -o wheels -u ritchie46

Edit: removing -i python does not work, it's due to a bug in maturin, but I think you can workaround it with -i python3.7.
