python-2.7 - Windows 上的 VPython 安装错误

Question

>>> import visual
RuntimeError: module compiled against API version 9 but this version of numpy is 7

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import visual
  File "C:\Python27\lib\site-packages\visual\__init__.py", line 3, in <module>
    from visual.visual_all import * # this statement not included in vis/__init__.py
  File "C:\Python27\lib\site-packages\visual\visual_all.py", line 10, in <module>
    from visual_common.cvisual import vector
ImportError: numpy.core.multiarray failed to import

当我尝试在 2.7.9 上导入视觉时出现此错误有什么问题？
