PYTHONPATH被忽略 [英] PYTHONPATH ignored
问题描述
环境：debian 4.0
Environment: debian 4.0
Python 2.4
Python 2.4
我的项目安装在：
/usr/lib/python2.4/site-packages/project。
/usr/lib/python2.4/site-packages/project.
但是，我想使用我的工作副本而不是位于以下的已安装的副本：
But I want to use my working copy instead of the installed one which is located in:
/ home / me / dev / project / src
/home/me/dev/project/src
是：
export PYTHONPATH = / home / me / dev / project / src
export PYTHONPATH=/home/me/dev/project/src
ipython
import foo＃在src中
import foo # which is in src
foo .__ file __
*/usr/lib/python2.4/site-packages/project/foo.py*
而不是：
/home/me/dev/project/src/project/foo.py
/home/me/dev/project/src/project/foo.py
怎么来我试着检查一下这个pathes（已经做了上面的导出），我看到的是：
How come? I try to check the pathes (having done the export above) and what I see is:
import sys，os
import sys,os
sys.path
[''，
'/ usr / bin'，
'/usr/lib/python2.4/site-packages'，
'/ home / me / dev / project / src'，
'/usr/lib/python24.zip'，
'/usr/lib/python2.4'，
'/usr/lib/python2.4/plat-linux2'，
'/usr/lib/python2.4/lib-tk'
'/usr/lib/python2.4/lib-dynload'，
'/usr/local/lib/python2.4/site-packages'，
'/ usr / lib / python2.4 / site-packages / PIL'，
'/var/lib/python-support/python2.4'，
'/usr/lib/python2.4/site-packages/IPython/扩展'，
'/home/me/.ipython']
os.environ ['PYTHONPATH']
os.environ['PYTHONPATH']
/ home / me / dev / project / src
推荐答案
根据python文档，这是e预期行为： https://docs.python.org/2.4 /lib/module-sys.html ：
According to python documentation, this is expected behavior: https://docs.python.org/2.4/lib/module-sys.html:
请注意，脚本目录是
插入之前
Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.
在python-2.6下，它是不同的： http://docs.python.org/tutorial/modules.html#模块搜索路径
Under python-2.6 it is different: http://docs.python.org/tutorial/modules.html#the-module-search-path
