[Erp5-users] Error in importation of Constraint

[Vincent Derrien]

Hi,

I've installed ERP5 on a Zope 2.7.2 but when I'm launching runzope I've the 
next error :

File "/usr/local/www/Zope/Products/ERP5Type/Utils.py", line 39, in ?
   from Products.ERP5Type import Constraint
ImportError : cannot import name Constraint

Do you have an idea about this error ?

Best regards,
