当我尝试使用 pip install scipy 安装 scipy 时，它失败并出现以下回溯

我使用的是 Mountain Lion，以及使用自制软件安装的 python 2.7.3，而 numpy 是使用 pip install numpy 安装的。

为什么 scipy 安装失败？

这似乎是 pip 和 numpy 的问题，它不会将编译后的库复制到 site-packages 目录中。

您可以使用 pip 安装到 virtualenv（对我有用）或使用

python setup.py install

方法。

这里有一些关于问题的评论：

如果您使用自制软件，您可以尝试以下方法（感谢https://github.com/pypa/pip/issues/707）：

brew tap samueljohn/homebrew-python
brew install numpy
brew install scipy

如果您不使用virtualenv，则可以手动编辑最少的侵入性修复/usr/local/lib/python2.7/site-packages/pip-1.2.1-py2.7.egg/pip/locations.py（您的 pip 版本可能会有所不同）。只需将第 35 行替换为：

build_prefix = os.path.join(tempfile.gettempdir(), 'pip-build')

到：

build_prefix = os.path.realpath(os.path.join(tempfile.gettempdir(), 'pip-build'))

此更改后，您需要重新安装numpy( pip uninstall numpy; pip install numpy)。然后scipy可以通过 pip 正确安装。

该问题是由 pip 错误引起的。上面的解决方案是根据github用户qwcode的pip补丁（在Lokkju提到的问题讨论中建议的）。此补丁似乎已合并到主 pip 存储库。但是，我看不到 brew update pip 的简单方法，因为它与 Python 捆绑在一起。所以只需手动进行这个简单的修复对我有用。

我在 2015 年使用 MacOSX Yosemite 时遇到了同样的问题。我认为这是由 pip 的旧版本错误引起的。卸载 pip 并获取它的最新版本会有所帮助。从https://pip.pypa.io/en/latest/installing.html获取 pip 然后

$ sudo pip uninstall scipy
$ sudo pip install scipy
