在Python 3.3中导入ggplot时出错

Question

pip安装很顺利但是当我尝试将模块导入shell时出现以下错误：

Traceback (most recent call last):   File "<pyshell#1>", line 1, in <module>
    from ggplot import *   File "C:\Python33\lib\site-packages\ggplot\__init__.py", line 21, in <module>

    from ._ufuncs import * ImportError: DLL load failed: The specified module could not be found.

我是一个初学者，所以不要排除明显的东西。
