linux 添加python 模块搜索路径(以thrift为例)

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
Python 2.7.8 (default, Nov  3 2016, 13:00:04) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 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
>>>
