IDLE和Python在Mac OS X中的路径不同

Question

我正在使用 Mac OS X 10.5.8 系统。我从网站上安装了 Python 2.6，安装在我的应用程序目录里。我修改了我的 .bash_profile 文件，内容是：

# Setting PATH for MacPython 2.6
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.6/bin:${PATH}"
export PATH
export PATH=/usr/local/mysql/bin:/Library/Frameworks/Python.framework/Versions/2.6/bin:/Library/Frameworks/Python.framework/Versions/2.6/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
export PYTHONPATH=/Users/blwatson/pythonpath:/Users/blwatson/pythonpath/django/bin:$PYTHONPATH

当我在命令提示符下运行 python 时，我可以看到以下内容：

Python 2.6.2 (r262:71600, Apr 16 2009, 09:17:39) 
[GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> django.VERSION
(1, 0, 4, 'alpha', 0)

正在检查 PATH

>>> import sys
>>> sys.path
['', '/Users/blwatson/pythonpath', '/Users/blwatson/pythonpath/django/bin', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python26.zip', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-darwin', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/plat-mac/lib-scriptpackages', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-tk', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-old', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/PIL', '/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/wx-2.8-mac-unicode']
>>>

但是当我在 IDLE 中时，体验就不一样了。

Python 2.6.2 (r262:71600, Apr 16 2009, 09:17:39)

我完全不知道发生了什么。我从一台笔记本电脑换到另一台，并且做了 TimeCapsule 的备份，所以我知道可能因为这个原因出现了一些冲突。IDLE 是从哪里获取 PATH 的呢？为什么我不能导入 Django 呢？

django idle mac os x command-line python installation __path__ bash_profile time capsule
