"AttributeError: fileno" when attemping to import from pyevolve

I just installed Pyevolve using开发者_运维知识库 easy_install and I am getting errors trying to run my first program. I first tried copy and pasting the source code of the first example but this is what I receive when I attempt to run it:

Traceback (most recent call last):

AttributeError: fileno

I am running python 2.6 on Fedora 11 X86_64.

Edit: After looking into it more if I run python from the command line it works but it only fails when I'm running IDLE.

Have you tried to check out the Development version ? It's near of the RC1, so it is stable right now: svn co https://pyevolve.svn.sourceforge.net/svnroot/pyevolve/trunk pyevolve

Your problem seems to be the paths, try uncompressing the "egg" file and put the "pyevolve" directory in the site-packages or inside your application directory.
