在osx上卸载scipy时遇到问题 [英] Have trouble uninstall scipy on osx

问题描述

我在使用2.7和3.4的多版本python时遇到了这个特定的麻烦. python2.7是由Apple本身安装的，而我自己安装了3.4，它的工作正常.
当我使用pip安装sklearn系列(scikit-learn numpy scipy)时，由于此pip已绑定到python3.4，因此python2.7无法使用它，而我的项目这次需要2.7.
我不会卸载3.4.

I've faced this specific trouble with multi-version python as 2.7 and 3.4. python2.7 was installed by apple itself and I installed 3.4 myself and it works just fine.
When i use pip to install sklearn series(scikit-learn numpy scipy), since this pip was bound to python3.4 so python2.7 couldnt use it, and my project needs 2.7 this time.
I'm not going to uninstall 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

this means my default version of python is 2.7

我的问题是我何时使用pip install&只需使用pip进行卸载，python3.4中的其他功能就可以正常工作.
要将numpy和scipy安装到python2.7，我下载了这些软件包并找到了setup.py，并使用sudo python setup.py install运行它们.

numpy看起来不错，但是scipy遇到了这样的麻烦

My Question is when i use pip install & uninstall just with pip, the extras in python3.4 works fine.
And to install numpy and scipy to python2.7 I download those package and find those setup.py and run them with sudo python setup.py install.

The numpy seems fine but the scipy have this trouble as

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下运行此"sudo python setup.py install"(当然我失败了，发现我需要一个).而在获取gfortran之后，我就被这个烦人的错误所困扰.

我的计划是先用pip卸载scipy，但我无法面对这个问题

I run this "sudo python setup.py install" under scipy when i didnt have gfortran(of course i failed and find out that i need one). And after get gfortran im stuck with this annoying error.

my plan is uninstall scipy with pip first but i cant as im facing this

$ 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.

我不是说英语的人.对不起我的英语不好.



更新:正好解决了这个问题，并已解决了其他所有问题，例如熊猫或sklearn

Im very frustrated but still working on it. and seeking for help.

Im not an english speaker.so sorry for my poor english.



UPDATE:just with this problem and ive fix all others like pandas or sklearn
