Unable to install django-toolkit with a python virtualenv

Question

I'm relatively new to Python, Django and Heroku. I'm attempting to follow the instructions on setting up a Django Heroku project found here. I'm getting stuck at the following command:

$ pip install django-toolbelt

I get the following error

django\contactmanager\venv\lib\site-packages

According to this link I'm supposed to install python-dev, python-psycopg2, libpq-dev before installing django-toolbelt.

I'm on a Windows machine. How can I install these dependencies? I tried installing them with pip but that doesn't work.

Apparently psycopg2 installers do not work under a virtualenv environment. I downloaded an executable binary from http://stickpeople.com/projects/python/win-psycopg/

To install the native binary in a virtual envrionment, use easy_install:

C:\virtualenv\Scripts\> activate.bat
(virtualenv) C:\virtualenv\Scripts\> easy_install psycopg2-2.5.win32-py2.7-pg9.2.4-release.exe

This blog post seems useful for your case:

http://www.swarley.me.uk/blog/2014/02/24/create-a-django-development-environment-on-64-bit-windows-for-heroku-deployment/

Or you can just find the windows ports for these dependency packages.
