以thrift为例
安装后会显示安装路径（红色部分）
Installed
/usr/lib/python2.6/site-packages/thrift-0.10.0-py2.6-linux-x86_64.egg
Processing dependencies for thrift
Finished processing dependencies for thrift
导入模块失败
>>> from thrift import Thrift
Traceback (most recent call last):
File “<stdin>”, line 1, in <module>
ImportError: No module named thrift
查看python 模块默认安装路径
>>> import sys
>>>
>>> print sys.path
[”, ‘/usr/local/python/lib/python27.zip’, ‘/usr/local/python/lib/python2.7’, ‘/usr/local/python/lib/python2.7/plat-linux2’, ‘/usr/local/python/lib/python2.7/lib-tk’, ‘/usr/local/python/lib/python2.7/lib-old’, ‘/usr/local/python/lib/python2.7/lib-dynload’,
‘/usr/local/python/lib/python2.7/site-packages’
]
增加.pth文件（文件名随便取，我用test）
cd
/usr/local/python/lib/python2.7/site-packages
[ee@ee site-packages]$
sudo vim test.pth
/usr/lib/python2.6/site-packages/thrift-0.10.0-py2.6-linux-x86_64.egg
导入成功
[ee@ee ~]$ python

>>> from thrift import Thrift

方法二，添加临时模块
>>> import sys
>>> sys.path.append(‘/usr/lib/python2.6/site-packages/thrift-0.10.0-py2.6-linux-x86_64.egg’)
>>>
>>> from thrift import Thrift
>>>
