错误：似乎scikit-learn还没有正确构建

Question

我正在运行Mac OS 10.10.5。和Python 3和XCode 7.2.1。我用pip（PyCharm）安装了SciKit-Learn及其所有依赖项，当我尝试使用该软件包时出现此错误。我在另一台运行10.10.5的计算机上尝试过，但没有收到错误。以下是完整的错误消息：

/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5 /Users/jonathankogan/PycharmProjects/Test/test.py
Traceback (most recent call last):

    from ._check_build import check_build
ImportError: dynamic module does not define module export function (PyInit__check_build)

During handling of the above exception, another exception occurred:

It seems that scikit-learn has not been built correctly.

If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.

If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.
