Document installation for OSX (cannot import name constants)

I am trying to install Graphite. I am stuck upon cairo installation. I came across “http://stackoverflow.com/questions/11491268/install-pycairo-in-virtualenv”. I have installed cairocffi in my virtual environment.

My environment is: “OS X: 10.8.5 Python: 2.7.2 Virtual Env: pip list cairocffi (0.5.1) ceres (0.10.0) cffi (0.8.1) Django (1.5.5) django-tagging (0.3.1) pip (1.5) pycparser (2.10) setuptools (2.0.2) Twisted (11.1.0) txAMQP (0.6.2) whisper (0.9.12) wsgiref (0.1.2) zope.interface (4.0.5)”

Cairo: I have installed cairo using macports. “cairo @1.12.16_2+x11 (active)”

I started graphite with following sequence of commands:

1. source /opt/graphite/bin/activate
2. sudo /opt/graphite/bin/carbon-cache.py start
3. sudo ./bin/run-graphite-devel-server.py /opt/graphite

http://0.0.0.0:8080/ is displaying Graphite home page. But http://0.0.0.0:8080/render produces following traceback:

I don’t know why, but apt-get install python-cairo-dev fixed my issue (same as OP)

Thanks for the answer all above, I met this problem yesterday. By reading your answers, it solved by "brew install cairo"finnally lol
