在Mac 10.8.2上安装Numpy

Question

我在MacOS 10.8.2上运行python 2.6,并尝试安装Numpy以使用NLTK.我已经看过下面突出显示的几种方法,但是我还没有运气包安装.

1. 我按照这个建议安装了xcode ,但这还没有解决任何问题.

2. 我尝试直接使用

   python setup.py build --fcompiler=gnu95
   

   返回以下消息

   RuntimeError: Broken toolchain: cannot link a simple C program
   

3. 直接安装,我从这里下载了dmg文件.直接提取文件时,numpy抱怨它需要安装Python 2.6或更高版本,因此也会失败.

   我在某地读过MacOS附带Apple版的Python,我想避免使用它; 我已经安装了Eclipse和PyDev,并且相信我没有使用Apple版本,但有没有办法确认这是真的并且numpy正在安装在"正确"的Python版本上？

4. 当我试着跑

   sudo easy_install numpy

   我得到以下输出.最初我认为它与找不到的C/Fortran编译器有关,但我gfortran在直接构建时安装了,所以也许问题就是其他问题...我无法诊断问题,看看剩下的但是消息.

是否有人能够指出一些确定性的东西可以帮助我安装numpy完毕？什么 - 如果有的话 - 到目前为止我试过的是错的？

提前谦卑地谢谢你!

Answer 1

这就是我解决这个问题的方法:

export CC=gcc
export CXX=g++
export FFLAGS=ff2c

基于我在10.7安装说明中找到的信息:http: //www.scipy.org/Installing_SciPy/Mac_OS_X

Answer 2

这里有一条评论说苹果版本的 python 2.7 附带了 numpy，所以你根本不需要安装它。

尝试跑步

>>> /usr/bin/python2.7
Python 2.7.2 (default, Jun 20 2012, 16:23:33) 
[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy

应该可以正常工作。现在您只需将系统 Python 2.7 配置为默认版本，并为此安装 NLTK。

我还找到了为什么安装 xcode 后仍然失败的解决方案gcc。您需要单独安装命令行工具。看看这个帖子。
