在 Mac OS X Mountain Lion 上，我尝试 

import numpy as np
import os
import statsmodels.api as sm

我收到此错误：

    /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python /Users/idf/PycharmProjects/PyAlgoTrade/GoldvsMiners.py
Traceback (most recent call last):
  File "/Users/idf/PycharmProjects/PyAlgoTrade/GoldvsMiners.py", line 9, in <module>
    import statsmodels.api as sm
  File "/Library/Python/2.7/site-packages/statsmodels-0.0.0-py2.7-macosx-10.8-intel.egg/statsmodels/api.py", line 1, in <module>
    import iolib, datasets, tools
ImportError: No module named iolib

如果我添加

import sys
print("=======")
print sys.path
print("=======")

我明白了

我曾尝试在网上搜索，但我被困在这个网上。有任何想法吗？
