How to easy_install psycopg2 on windows 7?

While following this tutorial to setup osqa. I got into the line direct you to run:

easy_install.exe psycopg2

I had located vcvarsall.bat under C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC and added the full path of it to %PATH% but still get the following error:

error: Setup script exited with error: Unable to find vcvarsall.bat

Here is the full cmd output:

C:\>easy_install.exe psycopg2

Save yourself some grief and download it from this website where you'll find compiled installers for many Python libraries for Windows. I highly recommend bookmarking this if you are using Python on Windows.

Make sure you download the correct one for the version of Python you are using. These installers work with the official Python installer (from python.org), as they read the registry value for the installer location and do the rest of the magic.

As these are Windows installer packages, just double click and follow the prompts.

Download the binary installer and use that.

Windows is a huge pain for software installation from source code. Unless you're already set up with a development environment, just use the binary installer.

It's a pity that easy_install, pip, etc don't do this automatically.
