Answer 1

对我来说（Mac OS X Maverics，Python 2.7）

easy_install --upgrade numpy

帮助。之后，您可以使用pip安装最新软件包pandas，scikit-learn等：

pip install pandas

Answer 2

我发现它是一个过时或不匹配的简单版本，并通过以下方式修复：

pip install --upgrade numpy

pip install --upgrade scipy

pip install --upgrade pandas

或者可以使用一种衬板：

pip install --upgrade numpy scipy pandas
