我已經遇到了多版本python 2.7和3.4的特定問題。 python2.7由蘋果公司自己安裝，我自己安裝3.4，它工作得很好。
當我使用pip安裝sklearn系列（scikit-learn numpy scipy）時，由於此pip綁定到python3.4，所以python2.7無法使用它，並且此時我的項目需要2.7。
我不打算卸載3.4。
無法在osx上卸載scipy
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.
這意味着我的Python的默認版本是2.7
我的問題是當我使用pip install &只是PIP卸載，在python3.4的額外工作正常。
並安裝numpy和scipy到python2.7我下載這些軟件包並找到setup.py並使用sudo python setup.py install來運行它們。
的numpy的似乎不錯，但SciPy的有此煩惱的
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
我下SciPy的運行此「sudo python setup.py install」當我沒有gfortran（當然我失敗了，發現我需要一個）。而後得到gfortran我堅持這個惱人的錯誤。
我的計劃是卸載SciPy的與PIP第一，但我不能作爲即時通訊面臨着這樣的

林非常沮喪，但它仍在工作。並尋求幫助。
我不是英語speaker.so對不起我的英文不好。
