Please try to run the command import psycopg2 on the python console  If you get the error then check the sys path where the python look for the install module  If the parent directory of the python-psycopg2-2 4 5-1 rhel5 x86 64 is there in the sys path or not  If its not in the sys path then run export PYTHONPATH  lt parent directory of python-psycopg2-2 4 5-1 rhel5 x86 64 gt  before running the openerp server

Use psycopg2-binary instead of psycopg2   pip install psycopg2-binary   Or you will get the warning below      UserWarning  The psycopg2 wheel package will be renamed from release 2 8  in order to keep installing from binary please use  pip install psycopg2-binary  instead  For details see  http   initd org psycopg docs install html binary-install-from-pypi    Reference  Psycopg 2 7 4 released   Psycopg
