Python添加默认模块搜索包路径

转载原文：http://blog.sina.com.cn/s/blog_59ba44680100z0mt.html

怎么样把自己写的模块加入到python默认就有的搜索路径中呢？不要每次非得import sys; sys.path.append(‘/home/fightlikekobe/python’)才可。

上网找了很多久未果，都来我自己糊里糊涂找到了解决方法，那就是在dist-packages（即/usr/local/lib/python2.7/dist-packages）添加一个路径文件，如mypkpath.pth，必须以.pth为后缀，写上你要加入的文件名称就是了，如我的：

/home/fightlikekobe/python

保存退出，OK！结果自己验证，重启terminal，再次打开python，

>>> import sys
>>> sys.path
['/home/fightlikekobe', '/usr/bin', '/usr/local/lib/python2.7/dist-packages/pymysql_sa-1.0-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/PyMySQL-0.5-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/hiredis-0.1.0-py2.7-linux-i686.egg', '/usr/local/lib/python2.7/dist-packages/SQLAlchemy-0.7.3-py2.7-linux-i686.egg', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/local/lib/python2.7/dist-packages','/home/fightlikekobe/python', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client', '/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch', '/usr/lib/python2.7/dist-packages/ubuntuone-installer', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol', '/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode']
