python django - no module psycopg2.extension even after installing compiled version psycopg2-2.4.5.win32-py2.7.‌exe

I am using python django on windows,and trying to deploy to heroku . When i tried to install psycopg2 using pip, ``` pip install psycopg2 ``` i got error : unable to find vcvarsall.bat Then i found that i need to install visual studio 2008 (or) i can directly download and install compiled version , so downlaoded from this link : http://www.lfd.uci.edu/~gohlke/pythonlibs/ Filename i downloaded : psycopg2-2.4.5.win32-py2.7.‌exe Even after installing this i am getting error : no module named psycopg2.extensions So, what more should i do ? ``` D:\mycode\python\mysite>heroku run python manage.py syncdb Running python manage.py syncdb attached to terminal... up, run.1 Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/app/.heroku/venv/lib/python2.7/site- packages/django/core/management/__i nit__.py", line 443, in execute_from_command_line utility.execute() File "/app/.heroku/venv/lib/python2.7/site-packages/django/core/management/__i nit__.py", line 382, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/app/.heroku/venv/lib/python2.7/site-packages/django/core/management/__i nit__.py", line 261, in fetch_command klass = load_command_class(app_name, subcommand) File "/app/.heroku/venv/lib/python2.7/site-packages/django/core/management/__i nit__.py", line 69, in load_command_class module = import_module('%s.management.commands.%s' % (app_name, name)) File "/app/.heroku/venv/lib/python2.7/site-packages/django/utils/importlib.py" , line 35, in import_module __import__(name) File "/app/.heroku/venv/lib/python2.7/site-packages/django/core/management/commands/syncdb.py", line 8, in <module> from django.core.management.sql import custom_sql_for_model, emit_post_sync_ signal File "/app/.heroku/venv/lib/python2.7/site-packages/django/core/management/sql .py", line 6, in <module> from django.db import models File "/app/.heroku/venv/lib/python2.7/site- packages/django/db/__init__.py", line 40, in <module> backend = load_backend(connection.settings_dict['ENGINE']) File "/app/.heroku/venv/lib/python2.7/site-packages/django/db/__init__.py", line 34, in __getattr__ return getattr(connections[DEFAULT_DB_ALIAS], item) File "/app/.heroku/venv/lib/python2.7/site-packages/django/db/utils.py", line92, in __getitem__ backend = load_backend(db['ENGINE']) File "/app/.heroku/venv/lib/python2.7/site-packages/django/db/utils.py", line24, in load_backend return import_module('.base', backend_name) File "/app/.heroku/venv/lib/python2.7/site-packages/django/utils/importlib.py" , line 35, in import_module __import__(name) File "/app/.heroku/venv/lib/python2.7/site-packages/django/db/backends/postgresql_psycopg2/base.py", line 13, in <module> from django.db.backends.postgresql_psycopg2.creation import DatabaseCreation File "/app/.heroku/venv/lib/python2.7/site- packages/django/db/backends/postgre sql_psycopg2/creation.py", line 1, in <module> import psycopg2.extensions ImportError: No module named psycopg2.extensions D:\mycode\python\mysite> ``` While isntalling psycopg2 both by pip and easy_install, installdidnt work as i got this error : unable to find vcvarsall.bat with some msg : no previsouly included directores matching 'doc\src_build' Thanks
