【问题描述】：
在尝试在我的机器上安装 scikit-learn 时，我遇到了问题。我正在使用 Homebrew 的 Python 2.7.5 运行 OS X 10.8.4，并且安装了最新版本的 Scipy 和 Numpy。
我尝试通过 Pip 安装 scikit-learn 以及克隆最新的源代码并从头开始构建 - 这是我每次尝试构建时都会得到的结果。知道这里发生了什么吗？

【问题讨论】：
-
NumPy 和 SciPy 版本到底是什么？
-
Numpy 为 1.7.1，SciPy 为 0.12.0。
-
这不是讨论错误的理想格式，但是您是否安装了 Cython？如果没有，请使用
pip install cython安装它吗？ -
已安装 cython，结果相同。我知道这并不理想，但我想我会确保在提交问题之前我没有做一些愚蠢的事情。我现在就去做，并从这里链接到它。
-
安装 Cython 并没有改变；我想建议你在
sklearn/feature_extraction/_hashing.pyx上运行 Cython，然后重新编译并重试。
