trying to install pymssql on ubuntu 12.04 using pip

Question

I am trying to install pymssql on ubuntu 12.04 using pip. This is the error I am getting. Any help would be greatly appreciated as I am completely lost!

Tried googling this but unfortunately to no avail...

Make sure you have the python-dev package installed (needed to compile packages with native bindings (thanks to @ravihemnani).

Then you'll need to install the FreeTDS development package (freetds-dev) before trying to install pymssql with pip:

$ sudo apt-get install freetds-dev

and then, in your virtualenv or wherever you wish to install it:

$ pip install pymssql
