在 osx 上卸载 scipy 时遇到问题

Question

我在 2.7 和 3.4 的多版本 python 中遇到了这个特定的问题。 python2.7 是苹果自己安装的，我自己安装了 3.4，效果很好。
当我使用pip安装sklearn系列（scikit-learn numpy scipy）时，由于这个pip绑定到python3.4所以python2.7无法使用它，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.

这意味着我的默认 python 版本是 2.7

我的问题是当我使用pip install 并仅通过 pip 卸载时，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，我下载了这些包并找到了那些 setup.py 并使用 sudo python setup.py install 运行它们。

numpy 看起来不错，但 scipy 有这个麻烦，因为

error: Command "/usr/local/bin/gfortran -Wall -g -ffixed-form -fno-second-underscore -arch x86_64 -fPIC -I/Library/Python/2.7/site-packages/numpy-1.12.0.dev0_d69c147-py2.7-macosx-10.11-intel.egg/numpy/core/include -c -c scipy/integrate/mach/d1mach.f -o build/temp.macosx-10.11-intel-2.7/scipy/integrate/mach/d1mach.o" failed with exit status 1

当我没有 gfortran 时，我在 scipy 下运行这个“sudo python setup.py install”（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，但我无法面对这个

$ 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。并寻求帮助。

我不是说英语的人。很抱歉我的英语不好。



更新：只是解决了这个问题，我修复了所有其他问题，例如 pandas 或 sklearn
