Scipy 安装到 Mountain Lion 上的错误位置? [英] Scipy Installing to Wrong Place on Mountain Lion?

问题描述

尝试在 Mountain Lion 上安装 scipy，除了:

Tried installing scipy on Mountain Lion, and couldn't get anything to work except:

sudo pip install -e git+https://github.com/scipy/scipy#egg=scipy-dev

sudo pip install -e git+https://github.com/scipy/scipy#egg=scipy-dev

我相信它安装了 scipy 的开发版本.出于某种原因，它在我当前的文件夹中留下了一个 src 目录，其中包含一个 pip-delete-this-directory.txt 和 scipy 目录，其中包含所有 scipy 文件.我可以从任何地方导入 scipy，但删除此文件夹会完全删除 scipy.怎么回事?

which I believe installs the development version of scipy. For some reason it leaves an src directory inside my current folder, which contains a pip-delete-this-directory.txt and scipy directory containing all scipy files. I can import scipy from anywhere, but removing this folder removes scipy entirely. What's going on?

如果我尝试使用简单的 sudo pip install scipy 进行安装，我会得到以下内容

If I try installing with simply sudo pip install scipy, I get the following

/System/Library/Frameworks/vecLib.framework/Headers/vecLib.h:22:4: error: "<vecLib/vecLib.h> is deprecated.  Please #include <Accelerate/Accelerate.h> and link to Accelerate.framework."

                #error "<vecLib/vecLib.h> is deprecated.  Please #include <Accelerate/Accelerate.h> and link to Accelerate.framework."

推荐答案

来自 pip 文档页面:

编辑模式包通常安装在站点包下，但是当您进行更改时，直接从签出的源代码树中运行包更有意义.可编辑"安装在站点包中创建一个 .pth 文件，扩展 Python 的导入路径以查找包:

Edit mode Packages normally install under site-packages, but when you’re making changes, it makes more sense to run the package straight from the checked-out source tree. "Editable" installs create a .pth file in site-packages that extends Python’s import path to find the package:

$ pip install -e path/to/SomePackage

所以这意味着你可以简单地通过运行来解决你的问题:

So this means you can simply solve your problems by running:

 $ sudo mv src/scipy/scipy /Library/Python/2.7/site-packages/

然后如果你想干净，你可以编辑文件以删除由 pip 添加的行:

And then if you want to be clean, you can edit the file to remove the line that was added by pip:

 $ sudo vim /Library/Python/2.7/site-packages/easy-install.pth
