Installing

Quick Install

Get PyGraphviz from the Python Package Index at http://pypi.python.org/pypi/pygraphviz

or install it with:

easy_install pygraphviz

and an attempt will be made to find and install an appropriate version that matches your operating system and Python version.

More download options are at http://networkx.lanl.gov/download.html

Installing from Source

You can install from source by downloading a source archive file (tar.gz or zip) or by checking out the source files from the Subversion repository.

Source Archive File

  1. Download the source (tar.gz or zip file).
  2. Unpack and change directory to pygraphviz-“version”
  3. Run “python setup.py install” to build and install
  4. (optional) Run “python setup_egg.py nosetests” to execute the tests

SVN Repository

  1. Check out the PyGraphviz trunk:

    svn co https://networkx.lanl.gov/svn/pygraphviz/trunk pygraphviz
  2. Change directory to “pygraphviz”

  3. Run “python setup.py install” to build and install

  4. (optional) Run “python setup_egg.py nosetests” to execute the tests

If you don’t have permission to install software on your system, you can install into another directory using the –prefix or –home flags to setup.py.

For example

python setup.py install --prefix=/home/username/python
or
python setup.py install --home=~

If you didn’t install in the standard Python site-packages directory you will need to set your PYTHONPATH variable to the alternate location. See http://docs.python.org/inst/search-path.html for further details.
