在OS X 10.7上,NumPy不会从1.5.1升级到1.6.2

我正在尝试更新/升级我的NumPy,但我失败了.我想我可能在不同的目录中安装了多个版本的NumPy,但默认情况下python导入旧版本.有帮助吗？

这是我的Python所在的位置：

Gonzo-vs-Kitties:~ brian$which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python

这是Python导入的版本：

Gonzo-vs-Kitties:~ brian$python
Python 2.7.3 (v2.7.3:70274d53c1dd,Apr  9 2012,20:52:43) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help","copyright","credits" or "license" for more information.
>>> import numpy
>>> print numpy.__version__
1.5.1
>>>

现在我使用easy_install升级NumPy：

Gonzo-vs-Kitties:~ brian$sudo easy_install --upgrade numpy

即使我升级后,NumPy仍然是旧版本：

>>> import numpy
>>> print numpy.__version__
1.5.1
>>>

这是我的sys.path：

>>> print sys.path

有任何想法吗？
