使用Python 2.7安装numpy Lion ?

I am working on a OS X 10.7 with Python 2.7 from python.org and XCode 4.2.

我正在使用python.org和XCode 4.2中的Python 2.7开发OS X 10.7。

Following these instructions, I tried changing the CC, CXX, and FFLAGS variables and install with sudo pip install numpy. However, the installation still looks for gcc-4.2.
按照这些说明，我尝试更改CC、CXX和fflag变量，并使用sudo pip安装numpy进行安装。但是，安装仍然需要gcc-4.2。
I tried installing gcc-4.2 through MacPorts but get that Error: gcc42 does not build on Snow Leopard or later.
我尝试通过MacPorts安装gcc-4.2，但是得到了这个错误:gcc42不构建在Snow Leopard或以后。
When I install numpy from the precompiled binary on sourceforge, I get the following error:

当我从sourceforge的预编译二进制文件中安装numpy时，我得到了以下错误:

import numpy

进口numpy

If I recall correctly the precompiled binary on source forge is 32-bit. It took me ages to get Numpy, Scipy, and Matplotlib set up on my macbook, it's definitely much harder than it should be.

如果我没记错的话，source forge上的预编译二进制文件是32位的。我花了很长时间才在我的macbook上安装了麻木、Scipy和Matplotlib，这肯定比应该的要难得多。

I believe that your best option is the Scipy superpack. Before using the superpack you need to update to Xcode 4.3.2

我相信你最好的选择是Scipy superpack。在使用superpack之前，您需要更新到Xcode 4.3.2

So I just installed python 2.7.2 from python.org, grabbed the superpack, and now have numpy working on my machine. After installing python 2.7.2, I did sudo pip uninstall numpy, which didn't remove enough. So I cd'd into /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ and moved both the numpy directory and the numpy egg to "old" versions of themselves. Then I ran sh install_superpack.sh and answered no to the "are you installing from a repository cloned to this machine(pretty important lol, hit yes without thinking the first time).

所以我刚从python.org上安装了python 2.7.2，抓住了超级包，现在我的机器上有了numpy。在安装了python 2.7.2之后，我做了sudo pip卸载，它没有移除足够的内容。因此，我将数据保存到/Library/ framework/ Python.framework/ version /2.7/lib/python2.7/site-packages/并将numpy目录和numpy egg都移动到它们自己的“旧”版本。然后我运行sh install_superpack。sh并回答“您是否正在从一个克隆的存储库安装到这个机器(非常重要的lol，不加思索地点击yes)”。

However, now I'm able to do this:

然而，现在我可以做到:

$ python
Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> import scipy
>>> import matplotlib

With no problems :)

没有问题:)

SuperPack worked for me (thanks, @Nolen) on OS X 10.8 (Mountain Lion) w/ XCode 4.5.1 installed.

SuperPack为我(谢谢，@Nolen)在OS X 10.8 (Mountain Lion) w/ XCode 4.5.1中工作。

Numpy worked for me using pip install numpy after step #1 below. But scipy would not install using pip. SuperPack fixed this.

Numpy在下面的步骤#1之后使用pip安装Numpy为我工作。但是scipy不会使用pip进行安装。SuperPack固定。

The only thing I did differently was to use HomeBrew to install Python as step #1, rather than download it manually.

我做的唯一不同的事情是使用HomeBrew将Python安装为步骤1，而不是手动下载。

Install Python (separate from version that comes with OS X 10.8)

安装Python(独立于OS X 10.8版本)
- brew install python --framework --universal
- brew安装python——框架——通用
- pushd /System/Library/Frameworks/Python.framework/Versions
- pushd /系统/图书馆/框架/ Python.framework /版本
- sudo rm Current
- sudo rm当前
- sudo ln -s /usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/Current
- sudo ln - s /usr/local/Cellar/python/2.7.3/Frameworks/Python.framework /版本/电流
- popd
- popd
Install SuperPack:

安装SuperPack:
- curl -o install_superpack.sh https://raw.github.com/fonnesbeck/ScipySuperpack/master/install_superpack.sh
- curl - o install_superpack。sh https://raw.github.com/fonnesbeck/ScipySuperpack/master/install_superpack.sh
- sh install_superpack.sh
- sh install_superpack.sh
- (type your admin password several times during the installation...)
- (在安装过程中多次输入管理密码…)
