sqlalchemypyramidzope

Not able to import ZopeTransactionExtension from command line

I have a pyramid application and it has this line

from zope.sqlalchemy import ZopeTransactionExtension

It works without any issues

But if I try the same with command line I get

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named sqlalchemy

and 

from zope.sqlalchemy.datamanager import ZopeTransactionExtension
ImportError: No module named sqlalchemy.datamanager

I am not really sure why this is so. The docs have the same line and it seems to work for them at least

Solution

  • This sounds like an issue with mixing pip and easy_install (which setup.py develop uses). They do not cooperate well together when it comes to namespaced packages like zope.*. I suggest recreating your virtualenv.
