Python在bash的PYTHONPATH中找不到库时，在sys.path中声明。

Question

此Python脚本显示其路径包含/home/web/public_html/module/disc/static/python/lib/python2.4/site-packages：

$ python serverTest.py 
This is my sys.path:
['/home/web/public_html/module/disc/static/python/lib/python2.4/site-packages', 
 '/home/web/public_html/module/disc/static/python',
 '/usr/lib64/python24.zip',     
 '/usr/lib64/python2.4',
 '/usr/lib64/python2.4/plat-linux2',
 '/usr/lib64/python2.4/lib-tk', 
 '/usr/lib64/python2.4/lib-dynload',
 '/usr/lib64/python2.4/site-packages', 
 '/usr/lib64/python2.4/site-packages/Numeric',
 '/usr/lib64/python2.4/site-packages/gtk-2.0',
 '/usr/lib/python2.4/site-packages']

Traceback (most recent call last):
  File "serverTest.py", line 27, in ?
    import simplejson as json
ImportError: No module named simplejson

$ export PYTHONPATH=$PYTHONPATH:/home/web/public_html/module/disc/static/python/lib/python2.4/site-packages

$ python serverTest.py 
Hello, world!

可以看出，虽然目录在sys.path中，但脚本找不到安装在那里的simplejson。但是，当我在Bash中将相同的路径添加到PYTHONPATH时，就会发现simplejson。如何修复它，使simplejson在不设置Bash变量的情况下可用？在
