python - 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 .qplot import qplot   File "C:\Python33\lib\site-packages\ggplot\qplot.py", line 6, in <module>

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

我是一个初学者，所以不排除明显的东西。
