Backend subprocess exited when trying to invoke build_sdist #507

Hi,

Recent pandas uses mesonpy for buidling. Trying to install mesonpy from source on Slackware64-current gives an error I cannot place.

    Found ninja-1.11.1 at /usr/bin/ninja
    + meson dist --allow-dirty --no-tests --formats gztar                           
    Dist currently only works with Git or Mercurial repos

    ERROR Backend subprocess exited when trying to invoke build_sdist

Building a Slackware-installable python package is done with 

  python3 -m build --no-isolation
  python3 -m installer -d "$PKG" dist/*.whl

Do you have an idea what is missing to get the package built?

You are trying to rebuild an sdist from outside a git repo. If you already downloaded an sdist, you should run python3 -m build --wheel --no-isolation so that build doesn't try to build an sdist from another sdist (that cannot work).

Fab, including --wheel worked; thanks a lot !
