How do I force my code to use 32-bit Python in a virtual environment?

Question

Title pretty much says it all. Python 2.7.8, OSX 10.8.5 Already tried (separately) all the methods on:

arch -i386 /usr/local/bin/python

and

defaults write com.apple.versioner.python Prefer-32-Bit -bool yes

and

export VERSIONER_PYTHON_PREFER_32_BIT=yes

When I jump into the interpreter and run import platform; platform.architecture() I still get

('64bit', '') for each one.

sys.maxsize > 2**32 returns True

platform.architecture() is unreliable on OSX, to be sure you're still runing 64 bit and not 32 you should run sys.maxsize > 2**32

That returns True, which if I'm understanding the docs correctly means it's running 64-bit. How do I force 32? – thumbtackthief Aug 24 '14 at 18:02

Ah, running it in `arch -i386 /usr/local/bin/python` works. Thanks! – thumbtackthief Aug 25 '14 at 14:44
