无法识别PyXB模块

Question

我已经按照常规方式安装了setup.py模块(python pyxb安装)，下面是输出：

Found bundle in pyxb/bundles/common
Found bundle in pyxb/bundles/dc
Found bundle in pyxb/bundles/wssplat
Found bundle in pyxb/bundles/saml20
running install
running build
running build_py
running build_scripts
running install_lib
running install_scripts
changing mode of /usr/local/bin/pyxbgen to 755
changing mode of /usr/local/bin/pyxbwsdl to 755
changing mode of /usr/local/bin/pyxbdump to 755
running install_egg_info
Removing /usr/local/lib/python2.7/dist-packages/PyXB-1.2.4.egg-info
Writing /usr/local/lib/python2.7/dist-packages/PyXB-1.2.4.egg-info

然而，我一直收到这样的信息：

ImportError: No module named pyxb

运行包含以下内容的脚本时：

import pyxb
import pyxb.binding
import pyxb.binding.saxer
import StringIO
import pyxb.utils.utility
import pyxb.utils.domutils

有人知道为什么会发生这种情况吗？

事实证明，这是一个权限问题:当以sudo身份运行脚本时，它成功地导入了pyxb。安装pyxb的setup.py脚本为：drwxr-s--- 7 root staff 4096 May 19 16:30 pyxb
