在osx上卸载scipy时遇到问题

Question

我在使用多版本python as2.7和3.4时遇到过这个问题。 python2.7是由苹果自己安装的，我自己也安装了3.4，它运行得很好。
当我使用pip安装sklearn系列（scikit learn numpy scipy）时，因为这个pip绑定到python3.4，所以python2.7不能使用它，我的项目这次需要2.7。
我不会卸载3.4。

sh-3.2# python
Python 2.7.10 (default, Oct 23 2015, 18:05:06) 
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

这意味着我的python默认版本是2.7

我的问题是，当我使用pip install&uninstall时，python3.4中的附加功能可以正常工作。
为了将numpy和scipy安装到python2.7中，我下载了这些包并找到了它们设置.py用sudo python运行它们设置.py安装。

numpy看起来不错，但是scipy有这样的麻烦

我在scipy下运行这个“sudo python setup.py install”，而我没有使用gfortran（当然，我失败了，发现我需要一个）。在得到gfortran之后，我陷入了这个恼人的错误。

我的计划是先用pip卸载scipy，但我不能面对这个问题

$ pip2.7 uninstall scipy
DEPRECATION: Uninstalling a distutils installed project (scipy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
Uninstalling scipy-0.13.0b1:

我很沮丧，但仍在努力。寻求帮助。

更新：只需这个问题，我解决了所有其他问题，如熊猫或sklearn
