问题描述

我几个月来一直在尝试为Python 3安装numpy，但是尽管有大量的Google搜索，甚至将其发布到numpy邮件列表中，但我仍未找到解决方案.

我设法通过MacPorts安装了它，但是不幸的是，似乎没有用于Python 3的MatPlotLib端口，这是我尝试安装numpy的主要原因...所以我有点卡住了.

在尝试从setup.py文件进行构建时，我始终遇到相同的错误.我已经在下面包含了终端输出.

感谢您提供的任何帮助，

亚当.

这是终端输出:

解决方案

好吧，我终于设法安装了 NumPy .不确定这是最好的方法，但它似乎有效！

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

之后，我必须 pip 进入我的系统路径(同样可能有更好的方法):

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

在安装了 distribution 和 pip 之后，我安装了 Nose ，NumPy需要进行测试或进行以下操作:

  1. 再次在终端中输入以下内容:
    • pip install nose

现在，我需要确保拥有最新版本的 Xcode :

  1. 从 AppStore 安装最新版本的 Xcode
  2. 如果您仍然有/Developer文件夹，则将其重命名为Developer-old(不确定以后是否会给我带来麻烦)
  3. 打开终端，并创建指向Xcode的AppStore版本的符号链接(单行):
    • sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer /Developer

所有这些都省去了安装 NumPy 的时间:

  1. 从以下位置下载 NumPy 源: http: //sourceforge.net/projects/numpy/files/NumPy/1.6.2rc1/
  2. 取消存档文件
    3. 再次
  3. 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. 在 Terminal 中键入以下内容，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'(这是一行)
    • python3 setup.py build(这可能需要一段时间)
    • python3 setup.py install

好的，假设没有错误，请安装 NumPy .是时候测试一下了:

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

因此 NumPy 安装通过了除一项测试以外的所有测试，这看起来还不错.由于我仍在努力安装 matplotlib ，我还没有机会查看是否能正常工作...

希望这些说明对某人有用！

I have been trying for months to get numpy installed for Python 3 but despite copious amounts of Googling and even posting to the numpy mailing list I am still no closer to a solution.

I have managed to get it installed via MacPorts but unfortunately there doesn't appear to be a port of MatPlotLib for Python 3 which is the main reason I am trying to install numpy...so I am a bit stuck...

I keep getting the same error whilst trying to build from the setup.py file. I have included the terminal output below.

Thanks for any help you can offer,

Adam.

Here is the terminal output:

解决方案

Well, I finally managed to get NumPy to install. Not sure it is the best method but it seems to work!

First of all i needed to install distribute:

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

Then I installed pip:

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

After that I had to get pip on to my system path (again there are probably better ways):

  1. Open Terminal
  2. Type the following (single line):
    • sudo ln -s /Library/Frameworks/Python.framework/Versions/3.2/bin/pip /usr/local/bin

With distribute and pip installed I then installed Nose, which NumPy needs for testing or something:

  1. Again, in Terminal type the following:
    • pip install nose

Now I needed to make sure I had the latest version of Xcode:

  1. From the AppStore install the latest version of Xcode
  2. If you still have a /Developer folder then rename it Developer-old (not sure whether this will cause problems for me later or not)
  3. Open Terminal and create a symlink to the AppStore version of Xcode (single line):
    • sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer /Developer

With all of that out of the way time to install NumPy:

  1. Download the NumPy source from: http://sourceforge.net/projects/numpy/files/NumPy/1.6.2rc1/
  2. Unarchive the file
  3. Open Terminal again:
    • cd into the directory created by unarchiving the file e.g.
      • cd /Users/username/Downloads/numpy-1.6.2rc1
  4. Type into the Terminal the following to change the complier used to build NumPy:
    • 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' (this is a single line)
    • python3 setup.py build (this may take a while)
    • python3 setup.py install

Okay, assuming there were no errors NumPy should be installed. Time to test it out:

  1. Open IDLE
  2. In the Python Shell type:
    • import numpy
    • numpy.test('full')
  3. This will test NumPy the final result I received with Python 3.2.3 was:
    • <nose.result.TextTestResult run=3192 errors=0 failures=1>

So the NumPy installation passes all except one test, which seems pretty good. I haven't had a chance to see if works properly yet as I am still struggling to get matplotlib installed...

Hope these instructions are useful to somebody!

Adam.
