What version of Python are you using?
Hi there!
Our team at IBM are exploring the possibility of implementing one of our

Hi,
I have a question about Django. I easy_installed Django1.4 and psycopg2,
and python manage.py syncdb. And gave me a error; No module named
psycopg2.extensions. posgre9.1 is installed.
It works fine on my MAC but not my Windows. Does anyone know about
this issue
Hope to resolve this issue soon
