Well..

I think I can fix this by editing ez_setup.py

adding oneline after pkg_resources.DistributionNotFound is caught, in use_setuptools()

del pkg_resources, sys.modules['pkg_resources']

Not sure if this makes sense.

A patch based on 0.6c9.

Hmm, then it's strange.. Kenton (cc-ed) also got the same problem when running this on Ubuntu + python 2.6.
The pkg_resources is from /usr/lib/python2.6/dist-packages/, while the egg should have a higher import priority than /usr/lib/python2.6/dist-packages in sys.path...

Hi,

I got some error messages when using ez_setup to download and use the easy_install.

# setup.py
from ez_setup import use_setuptools
use_setuptools()

from setuptools import setup

setup(name = "blabla",
     test_suite = "some_test",
     namespace_package = ["some_namespace"],
           # many other options
)


So I guess there might be some import problem in my machine (ubuntu lucid) that the pkg_resources.py cannot be loaded from the egg?

Try running this script in your project directory:


  from ez_setup import use_setuptools
  use_setuptools()

  import sys, setuptools, pkg_resources
  print sys.path
  print pkg_resources.__file__
  print setuptools.__file__

This should tell us what's going on with your "import problem" more specifically.  ;-)
