我在我的mac os x上为python 2.7.3成功构建/安装了NumPy.现在我想建立/安装scipy.我从git hub下载了它.进入目录.Ran python setup.py build,它似乎一直在工作,直到遇到这个错误:

我正在使用Python进行线性代数课程的编程.对于我们需要的工具,我正在尝试安装NumPy.我用这个网站来指导我完成安装过程.

我从SciPy OS X页面上的链接开始,最终到达SourceForge下载站点.

从那里,我选择了Mac OS X安装程序numpy-1.6.1-py2.7-python.org-macosx10.3.dmg.

当我去Idle并输入时

>>> import numpy as np

这是我收到的错误:

所以我按照本网站http://www.scipy.org/Installing_SciPy/Mac_OS_X上的说明,下载了Xcode和Fortran Gcc,然后从终端运行以下内容:
