Description Guillaume BINET 2012-11-07 22:28:35 UTC
I am confused about this one and still wonder if it is something specific about my install.

------------------------------------------------------------------------------
eselect python set python2.6; emerge -1 dev-python/pylint
works.

------------------------------------------------------------------------------
eselect python set python2.7; emerge -1 dev-python/pylint 
results in :
[...]
AttributeError: Distribution instance has no attribute 'namespace_packages'

at python setup install phase




Reproducible: Always

Steps to Reproduce:
eselect python set python2.7; emerge -1 dev-python/pylint 
Actual Results:  
eselect python set python2.7; emerge -1 dev-python/pylint 
results in :

Comment 1 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2012-11-08 06:52:49 UTC
I am confused too, it builds fine for me. As a formality, could you attach the full build log, and `emerge '-pv' pylint setuptools python`?
Comment 2 Ian Delaney (RETIRED) gentoo-dev 2012-11-22 13:20:00 UTC
I'm not quite so confused. 'namespace_packages' has a familiar ring. Please paste / post  output of

Comment 4 Guillaume BINET 2012-12-05 23:58:15 UTC
I found a "solution" to this :
for any package with this error (AttributeError: Distribution instance has no attribute 'namespace_packages')

1. unmerge setuptools
2. modify the package in my private overlay and remove the setuptools dependency
3. emerge the package successfully
4. reemerge setuptools which is a real dependency for other packages

I dichotomized this problem by doing a "python setup.py" build directly from the source package in a virtualenv that worked correctly and got a usr/lib64/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'namespace_packages'
  warnings.warn(msg)

for the same source tree under my gentoo python environment.

I hope it will help you finding what is really going on.
Comment 5 SpanKY gentoo-dev 2015-07-28 07:57:08 UTC
python2.6 is no longer supported and pylint in the tree def works with python2.7
