Installing the igraph package for python

Question

Dear Pythonistas,

I have downloaded the igraph 0.5.4 tar ball for macosx Leopard 10.5.8. When I unpack it and then run:

sudo python setup.py install

I get the following long error message:

    Include path: /usr/include /usr/local/include
Library path:

Is this a bug or am i doing something wrong?

Answer 1

What you have downloaded is only the Python interface to the igraph library. The library itself is written in C, and you will have to install the C core of igraph first before trying to compile the Python interface.

Basically, you have three choices here:

1. Try to make use of the pre-compiled Mac OS X installer of igraph that is found on the PyPI page of igraph.

2. Compile and install the C core first and then try again with the compilation of the Python first. The source code of the C core can be downloaded from the igraph homepage.

3. Install brew and then install the C core of igraph using brew from the command line:

   $ brew install igraph
   

   The above command will download, compile and install the C core of igraph for you, after which you can continue with the compilation of the Python interface.
