提问by zelinka
I took a new clean install of OSX 10.9.3 and installed pip, and then did
我重新安装了 OSX 10.9.3 并安装了 pip，然后做了
pip install pandas pip install numpy
Both installs seemed to be perfectly happy, and ran without any errors (though there were a zillion warnings). When I tried to run a python script with import pandas, I got the following error:
两次安装似乎都非常愉快，并且运行时没有任何错误（尽管有无数警告）。当我尝试使用 import pandas 运行 python 脚本时，出现以下错误：

File "./moen.py", line 7, in import pandas File "/Library/Python/2.7/site-packages/pandas/__init__.py", line 6, in from . import hashtable, tslib, lib
File "numpy.pxd", line 157, in init pandas.hashtable (pandas/hashtable.c:22331)

open your python, check the imported version of your numpy.
打开你的python，检查你的numpy的导入版本。
It is very likely that you have multiple numpy installed and python always grab the old one, just make sure to delete the old one would fix the problem.
很可能你安装了多个 numpy 并且 python 总是抓取旧的，只需确保删除旧的即可解决问题。
>>> import numpy as np
>>> np.__version__
>>> np.__file__
#if numpy version <= 1.7 would have the error
#find the file and delete it from (np.__file__)
then install the latest numpy if you don't have it
如果没有，请安装最新的 numpy
