NumPy 不会在 OS X 10.7 上从 1.5.1 升级到 1.6.2

Question

我正在尝试更新/升级我的 NumPy，但失败了。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 会导入一个旧版本。有什么帮助吗？

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 来升级 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
>>>

这是我的系统路径：

>>> print sys.path

有什么想法吗？

检查你的 numpy 包的路径：

import numpy
print numpy.__path__

并检查是否是你刚刚安装的那个。
