python安装setup安装目录_python–setup.py安装位置？

我正在运行安装了

python 2.6和2.7的Mac OS X Lion 10.7.1.我已经制作了2.6我的默认版本.我正在尝试安装一个软件包,它安装到2.7.我的设置如下&＃xff1a;

~:hi› which python

/usr/bin/python

~:hi› python -V

Python 2.6.6

~:hi› python

>>> import sys

&＃39;/System/Library/Frameworks/Python.framework/Versions/2.6&＃39;

>>> sys.exec_prefix

&＃39;/System/Library/Frameworks/Python.framework/Versions/2.6&＃39;

它不应该安装在2.6站点包中吗&＃xff1f;我误解了这应该如何运作&＃xff1f;
