[Grok-dev] Re: latest grokproject produces " Error: Couldn't find a distribution for 'zope.app'. "

[Craeg Strong]

Problem solved!

The root cause for my troubles (as I understand it):
1) One or more python eggs in my system python lists "zope.app" as a 
dependency
2) There is no egg for "zope.app" available in the cheeseshop for 
easy_install to download

Perhaps it is because zope.app has now been broken down into its 
constituent parts, but I still have some older eggs that depend on it?
How did I get those older eggs?  Perhaps I typed "easy_install grok" by 
mistake sometime in the past, rather than using grokproject.
The end result is I seem to have lots of eggs in my system python 
site-package directory that probably don't need to be there-- they 
should rather be
located only in my local development "buildout-eggs" directory.

In any event, here is what I did in order to locate the offending eggs 
and fix them. 

1) become root
2) cd /usr/lib/python2.4/site-packages
3) find . -name requires.txt -exec grep -l zope.app$ {} \;
./zope.testbrowser-3.4dev_r73329-py2.4.egg/EGG-INFO/requires.txt
./zope.formlib-3.4dev_r73110-py2.4.egg/EGG-INFO/requires.txt
./zope.lifecycleevent-3.4dev_r72934-py2.4.egg/EGG-INFO/requires.txt
      Aha!  Now I know which packages need to be upgraded...
4) easy_install -U zope.testbrowser zope.formlib zope.lifecycleevent

Now grokproject works just fine.  I hope others may find this recipe 
helpful.
