The easiest way to install the latest stable version of Biff is via pip:

pip install biff

If this doesn’t work, you can try to build the latest developer version as described below.

Cloning, Building, Installing

The latest development version of Biff can be cloned from GitHub using git:

git clone git://

To build the project (from the root of the source tree, e.g., inside the cloned biff directory):

python build

To install the project:

python install


The internals of Biff are implemented in C and Cython. To build the Cython code, you’ll need to have installed GNU scientific library (GSL). On a Mac, I recommend installing this with Homebrew or anaconda. With anaconda, you can install GSL with:

conda -c install gsl

You’ll also need the following packages:
