在OS X 10.7.4上安装NumPy for Python 3.2.3

Question

我已经尝试了几个月来为Python 3安装numpy但是尽管有大量的谷歌搜索,甚至发布到numpy邮件列表,我仍然没有接近解决方案.

我已经设法通过MacPorts安装它但不幸的是,似乎没有Python 3的MatPlotLib端口,这是我试图安装numpy的主要原因...所以我有点卡住...

尝试从setup.py文件构建时,我一直收到同样的错误.我在下面列出了终端输出.

谢谢你尽你所能的帮助,

亚当.

这是终端输出:

好吧,我终于设法让NumPy安装了.不确定它是最好的方法,但它似乎工作!

首先我需要安装分发:

1. curl http://python-distribute.org/distribute_setup.py | python3

然后我安装了pip:

1. curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python3

从那以后,我必须得到点子上我的系统路径(同样有可能是更好的方法):

1. 开放式终端
2. 输入以下内容(单行):
   • sudo ln -s /Library/Frameworks/Python.framework/Versions/3.2/bin/pip /usr/local/bin

随着分发和点子安装然后我安装了鼻子,这NumPy的需求测试或东西:

1. 再次,在终端类型中,以下内容:
   • pip install nose

现在我需要确保我有最新版本的Xcode:

1. 从AppStore安装最新版本的Xcode
2. 如果你还有一个/Developer文件夹,那么重命名它Developer-old(不确定这是否会在以后给我带来问题)
3. 打开终端并创建一个符号链接到AppStore版本的Xcode(单行):
   • sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer /Developer

所有这些都是安装NumPy的时间:

1. 从以下网址下载NumPy源代码:http://sourceforge.net/projects/numpy/files/NumPy/1.6.2rc1/
2. 取消归档文件
3. 再次打开终端:
   • cd 进入通过取消归档文件创建的目录,例如
     • cd /Users/username/Downloads/numpy-1.6.2rc1
4. 键入以下终端以更改用于构建NumPy的编译器:
   • export CC=clang
   • export CXX=clang
   • export FFLAGS=-ff2c
   • export LDSHARED='clang -bundle -undefined dynamic_lookup -arch i386 -arch x86_64 -isysroot /Developer/SDKs/MacOSX10.6.sdk -g' (这是单行)
   • python3 setup.py build (可能还要等一下)
   • python3 setup.py install

好的,假设没有错误,应该安装NumPy.是时候测试一下了:

1. 打开IDLE
2. 在Python Shell类型中:
   • import numpy
   • numpy.test('full')
3. 这将测试NumPy我用Python 3.2.3收到的最终结果是:
   • <nose.result.TextTestResult run=3192 errors=0 failures=1>

因此NumPy安装除了一个测试外都通过了所有测试,看起来非常好.我还没有机会看到是否正常工作,因为我仍在努力安装matplotlib ......

希望这些说明对某人有用!

亚当.
