No.

Well it seems you already have psycopg2 installed for Python 2.7, it
just cannot find it. Here is a possible solution.

Open the Python 2.7 shell

import sys

then

sys.path

This will show a list of paths that Python 2.7 knows about. Look to see
if /usr/local/lib/python2.7/site-packages/ is listed.

If not, you can temporarily include it by doing:

sys.path.append('/usr/local/lib/python2.7/site-packages/')

and then

import psycopg2

If it is indeed installed in /usr/local/lib/python2.7/site-packages/ it
should load.

To make the change 'permanent' create a  *.pth file in one of the
directories shown when you first did sys.path, preferably a
site-packages one. In the file  put
'/usr/local/lib/python2.7/site-packages/ . Then name the file, say
usr_local.pth. Python adds directories in *.pth files to the sys.path.
