[jira] [Commented] (ARROW-1346) [Python] pypi packages compatible with setuptools

["Antony Mayi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-1346?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16121684#comment-16121684 ] 

Antony Mayi commented on ARROW-1346:
------------------------------------

I am on linux.

Yes, pip works fine, but setuptools is not using pip. Any version of setuptools (I am on the latest 36.2.7).

The attached [^setup.py] demonstrates the problem - ie if I am trying to distribute my python project that depends on pyarrow as per the [^setup.py] it won't pull pyarrow out of the box (running the typical {{python setup.py install}} fails as per the error shown above due to the setuptools inability to pull wheels from pypi).

> setuptools is internally using easy_install for pulling packages from pypi. easy_install doesn't support wheel so since pyarrow is in pypi distributed only as wheels it is not possible to package a product depending on pyarrow using setuptools.
> see attached [^setup.py]:
> {code}
> $ python setup.py test
> running test
> Searching for pyarrow==0.5.0.post2
> Reading https://pypi.python.org/simple/pyarrow/
> No local packages or working download links found for pyarrow==0.5.0.post2
> error: Could not find suitable distribution for Requirement.parse('pyarrow==0.5.0.post2')
> {code}
> It's a shame setuptools don't support wheels. unfortunately it supports only eggs or raw source packages (see [distro_for_location|https://github.com/pypa/setuptools/blob/master/setuptools/package_index.py#L112]). I am not suggesting providing eggs but perhaps publishing raw tar.gz should be considered so that setuptools can at least build the dependency itself.
