Writing idiomatic Python 3 code and supporting both Python 2 & 3 aren't really compatible goals. I suggest pointing to the stdlib implementation for the idiomatic Python 3 only code, and just targeting the common 2/3 subset for the PyPI version - a lot of people have been down this road before you and it really is the easiest way to do it :) > Is there a way to have both a Py2 distribution and a Py3 distribution > available on PyPI?

Perhaps you should do the same--only install the Python 2 tests on
Python 2 and so on. Just make sure that the MANIFEST.in is set up to
include both versions in the source distribution. As long as you
don't install the Py2 files in Py3 or vice versa it shoudn't try to
compile the bytecode for those files.
I would be willing to do that, but I don't know how, and so far my searching
hasn't yielded anything useful besides this mailing list.
Do this do what you want:
#setup.py
import sys
from distutils.core import setup
package_data = {'enum': [...]}
if sys.version_info >= (3,0):
package_data['enum'].append( 'test/py3_test_enum.py')
else:
package_data['enum'].append( 'test/py2_test_enum.py')
setup(package_data = package_data, ...)
Cool!
Is there a way to have files renamed? Ideally the installed package would just have enum.py, test_enum.py, and not
py2_enum.py and py2_test_enum.py

distutils is trying to load the py3 versions, which of course fails on a py2
install. The package installs successfully anyway, but if I were a user I
would be wondering if the install was trustworthy.
It seems to me that I need to either have distutils only install the version
appropriate files, or to not try to scan the version inappropriate files,
but at this point I do not know how to do either.
Any pointers would be greatly appreciated.
That's odd. I work on a package that ships Python 2 and Python 3
versions of some modules and I have never seen this problem before.
Perhaps you could post your setup.py?

That's correct. And you'll note that despite the scary-looking syntax

If I recall this is because it's trying to compile byte code.

That's odd. I work on a package that ships Python 2 and Python 3
versions of some modules and I have never seen this problem before.
Perhaps you could post your setup.py?

[Distutils] complicated setup
Here's my file layout:
/
|- setup.py
|
|- enum /
|- __init__.py
|
|- py2_enum.py
|
|- py3_enum.py
|
|- test /
|- test_enum.py
|
|- py2_test_enum.py
|
|- py3_test_enum.py
__init__ and test_enum are both smart enough to pull in the correct code when
imported. The issue I am having is this:

distutils is trying to load the py3 versions, which of course fails on a py2 install. The package installs successfully
anyway, but if I were a user I would be wondering if the install was trustworthy.
It seems to me that I need to either have distutils only install the version appropriate files, or to not try to scan
the version inappropriate files, but at this point I do not know how to do either.
Any pointers would be greatly appreciated.
