我正在尝试安装numpy，以便我可以在此之后安装biopython。我已经安装了pyton 2.7，当我在命令提示符下键入python时，我得到以下内容：
python
Python 2.7.4 (v2.7.4:026ee0057e2d, Apr 6 2013, 10:15:50)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
所以我确实有C编译器。现在，当我下载.ump of numpy和tdo时，请执行以下步骤：
> tar -xzvpf numpy-1.5.1.tar.gz
> cd numpy-1.5.1/
> python setup.py build
我得到了以下错误：

这是我的解决方案，转到： sourceforge 获取与我的python 2.7匹配的最新版本并简单安装。 感谢

看起来你错过了一个fortran编译器和setuptools。您是否安装了开发人员工具（Xcode或独立命令行工具）？对于setuptools，已经发布了大量类似的答案。只需谷歌错误消息。
那就是说，我建议可以通过一个简单的安装程序来查看Continuum Anaconda发行版以获得大部分python科学堆栈：
https://store.continuum.io/cshop/anaconda/
它附带了biopython并且是免费的。或者，还有包含biopython的Enthought Python Distribution：
