** Description changed:
Many packages now depend only on python-pkg-resources and not python-
setuptools, so the latter may be removed if it was automatically
installed. However, in that case the whole mechanism stops working:
$ python
>>> import pkg_resources
>>> pkg_resources.require('zope.interface')
Traceback (most recent call last):
- File "<stdin>", line 1, in <module>
- File "pkg_resources.py", line 648, in require
- needed = self.resolve(parse_requirements(requirements))
- File "pkg_resources.py", line 546, in resolve
- raise DistributionNotFound(req)
+ File "<stdin>", line 1, in <module>
+ File "pkg_resources.py", line 648, in require
+ needed = self.resolve(parse_requirements(requirements))
+ File "pkg_resources.py", line 546, in resolve
+ raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: distribute
This happens because zope.interface has setuptools in it's *.egg-
info/requires.txt, like many other packages, but in reality only needs
pkg_resources, and that's what is installed. Distribute is not needed at
all, so it is a bug that this breaks in such a way.
-
- As far as I can see this bug only occurs when require()'ing a python
- package using python-central. python-support using package is found
- successfully, e.g.
-
- >>> pkg_resources.require('Genshi')
- [Genshi 0.5.1 (/usr/share/pyshared)]
