Question

我遇到了多版本python的特殊问题，如2.7和3.4。 python2.7是由apple自己安装的，我自己安装了3.4并且工作得很好当我使用pip安装sklearn系列（scikit-learn numpy scipy）时，因为这个pip绑定到了python3.4所以python2.7无法使用它，这次我的项目需要2.7。
我不打算卸载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.

这意味着我的默认版本的python是2.7

我的问题是当我使用pip install＆amp;只需用pip卸载，python3.4中的附加工作正常。
并安装numpy和scipy到python2.7我下载这些包并找到那些setup.py并使用sudo python setup.py install运行它们。

numpy似乎很好，但scipy有这个麻烦

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

我执行此操作＆＃34; sudo python setup.py install＆＃34;当scaty我没有gfortran（当然我失败了，发现我需要一个）。并且在得到gfortran我坚持这个恼人的错误。
我的计划是首先卸载scipy，但我不能面对这个

$ pip2.7 uninstall scipy

我非常沮丧但仍在努力。并寻求帮助。

更新：刚刚解决了这个问题，我已经解决了所有其他问题，如熊猫或sklearn
