Python 2.7 在mac os X 10.10.2上安装pyo

我最近按照以下指南安装了pyo:and。然后我尝试在python上导入pyo，但出现了这种情况

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import pyo
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyo.py", line 21, in <module>
    import pyolib.analysis as analysis
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyolib/analysis.py", line 30, in <module>

  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pyolib/_core.py", line 32, in <module>

我能做什么？我是初学者，如果您需要其他信息，请告诉我。

找到解决方案：使用安装程序，无需其他。不过，我不知道为什么它没有任何其他的工作方式
