I use Python 3.3 as my default python install in OS X for use with multithreaded Automator actions and this breaks Houdini installation. It took me a while to figure out the problem so I'm wondering if you could make an explicit reference to /usr/bin/python2.7 instead of just /usr/bin/python , which is where I think the problem is.

you could install macport in your mac, and use
sudo port select –set python pythonXX (MacPorts 2.x)
sudo python_select pythonXX (MacPorts 1.x)
to set the python version explicitly.

Hello,

Houdini does not support Python 2.7 so you're stuck with using 2.6 or 2.5.

You can install older Python versions as suggested by hanton or download them straight from the Python website:
http://www.python.org/download/releases/2.6/ [python.org]

Cheers,
Rob

Actually, just to clarify, what's breaking because of Python 3.3?

Is it the Houdini installer? Or is it Houdini itself?

Does setting any of these 3 environmental variables help?

HOUDINI_PYTHON_VERSION, HOUDINI_PYTHON_LIB, HOUDINI_PYTHON_BIN

Houdini on OSX respects $HOUDINI_PYTHON_VERSION and $HOUDINI_PYTHON_LIB so you should be able to set either HOUDINI_PYTHON_VERSION=2.6 or HOUDINI_PYTHON_LIB=/System/Library/Frameworks/Python.framework/Versions/2.6/Python to force Houdini to use a particular Python version.

Note though that Python 2.7 is still not supported by Houdini.

sorry - late returning to this. The installer breaks, not Houdini.
