[Zope3-Users] Buildout fails with zope.recipe.egg 1.0.0 vs 1.0.0b6 conflict

[Jim Fulton]

Did zopepy previously specify "zc.recipe.egg ==1.0.0b6" as it's recipe?

Does zopepy have an uninstall recipe? I'd be interested in seeing  
your existing .installed.cfg and buildout.cfg.  You can send them to  
me privately. No need to inflict it on everybody else. :)

To work around this, I suggest adding:

   versions = versions

to your buildout section and adding the section:

   [versions]
   zc.recipe.egg = 1.0.0b6

This will force the buiodout to use 1.0.0b6 of zc.recipe.egg.
