py27-astropy @1.0.4: AttributeError: Distribution instance has no attribute 'exclude_package_data'

I'm trying to install py27-astropy-1.0.4_0 on a Mavericks machine and it's failing with the following:

Which version of setuptools do you have installed currently?

Which version of setuptools do you have installed currently?

$ port installed py27-setuptools
The following ports are currently installed:
  py27-setuptools @18.0.1_0 (active)

This looks like an issue with the installation of setuptools, given the following warnings:

Could you try and uninstall setuptools, clean, and install again, then try astropy again?

[skymoo (Adam Mercer)]

After uninstalling and reinstalling py27-setuptools I got the same error, I noticed that my system was downloading the package of py27-setuptools so I removed it again and forced a build from source. This also fails, the new main.log is attached​.

[robitaille@…]

I'm puzzled by this failure. The exclude_package_data option exists in setuptools since 0.6a9 which is a very old version. I just tried installing MacPorts from scratch and doing sudo port install py27-astropy and I don't see any issues, though this is on 10.8 (but not sure why this should matter?)

Do you have PYTHONPATH set by any chance?

[skymoo (Adam Mercer)]

Replying to robitaille@…:

Do you have PYTHONPATH set by any chance?

No.

$ echo $PYTHONPATH

[skymoo (Adam Mercer)]

Updated my ports tree, py27-setuptools was updated to 18.2_0 and py27-astropy to 1.0.4_0 and this still fails. Build log attached​.

[skymoo (Adam Mercer)]

Just tested on another machine, this one running Yosemite, and it built without issue on that. I have another Mavericks machine at work which I'll test on Monday...

[skymoo (Adam Mercer)]

On a Mavericks VM, running on a Yosemite host, py27-astropy builds fine. I've performed a clean MacPorts install on the machine I'm seeing this problem and it still fails with the same error. Any ideas about what could be different on this machine that could cause this?

AttributeError: Distribution instance has no attribute 'exclude_package_data'

Having faced this issue in a different context, the issue was most likely caused by the fact the installation of setuptools was done from its source tree available on ​https://github.com/pypa/setuptools and was NOT bootstrapped before being installed.

Not that installing using the source distribution available on pypi does not have problem.

To bootstrap before install, the following can be done:

cd setuptools
python bootstrap.py
python setup.py install

or if you prefer a non zipped version

cd setuptools
python bootstrap.py
python setup.py easy_install --always-unzip .

Omitting to bootstrap will prevent the file entry_points.txt for egg (or metadata.json for wheel) from being installed.

Without that file, the following code found in ​setuptools/dist.py#L319-L320@d8e1ed5 wouldn't extend distribution object with the setuptools specific keywords:

class Distribution(Distribution_parse_config_files, _Distribution):
    [...]
    def __init__(self, attrs=None):
        [...]
        for ep in pkg_resources.iter_entry_points('distutils.setup_keywords'):
            vars(self).setdefault(ep.name, None)
        [...]

py-astropy is now at version 4.0.3. I doubt this issue is still relevant.

[Schamschula (Marius Schamschula)]

Support for py27-astropy was dropped by ​https://github.com/macports/macports-ports/commit/c0a0799dde208526ad9a5556a6137c6a5c397df1
