Step 1: Install Python 2.7
python-igraph requires Python 2.5 and above. Do look at Installing and Compiling Python 2.7.8 on CentOS 5
Step 2: Download and unpack python-igraph from python-igraph.
The current version is python-igraph 0.7
Step 3: Unpack and compile
# tar -zxvf python-igraph-0.7.0 # cd python-igraph-0.7.0 # python setup.py install
If you encounter errors similar to /usr/lib64/libxml2.a: could not read symbols: Bad value
Step 4: Copy and update to /usr/local/
If you want to put all the packages in an easier to find directory. Copy
# mkdir -p /usr/local/python-igraph-0.7.0/bin # mkdir -p /usr/local/python-igraph-0.7.0/lib # cp $PYTHON-IGRAPH-HOME/build/scripts-2.7/igraph /usr/local/python-igraph-0.7.0/bin # cp -rv $PYTHON-IGRAPH-HOME/build/scripts-2.7/lib.linux-x86_64-2.7/igraph /usr/local/python-igraph-0.7.0/lib # cp -rv $PYTHON-IGRAPH-HOME/igraphcore/lib/libigraph.so* /usr/local/python-igraph-0.7.0/lib
Step 5: Test the python-igraph libraries.
Update .bashrc
export PATH=$PATH:/usr/local/python-igraph-0.7.0/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/python-igraph-0.7.0/lib
Test with python on the command line
$ python2.7 Python 2.7.8 (default, Jul 17 2014, 14:44:57) [GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import igraph >>>
*Easier Method*
You can use pip to install. For more information on how to install and use pip, see Installing and Compiling Python 2.7.8 on CentOS 5
