Hi peeople! I am trying to install zope3 /ztfy webapp, and I face quickly a problem by running "python bootstrap.py" after application setup. Here the problem: README.txt bootstrap.py buildout.cfg debug.ini deploy.ini etc extends-cache setup.py src var tamer@tux /storage/PyProjects/ztfyAPP $ python bootstrap.py Traceback (most recent call last): File "bootstrap.py", line 111, in <module> ws.find(pkg_resources.Requirement.parse(requirement)).location AttributeError: 'NoneType' object has no attribute 'location' what could it be?! I already spoke with somebody who had the same problem. He installed "zc.builout" globally, and it was solved for him but not me. My problem still exist even after installing through easy_install zc.buildout globally. Any ideas what it could be?! For any help I would kindly thank you Tamer
