ubuntu终端运行python找不到模块_在Ubuntu中找不到（但已安装）模块

安装lxml模块后，我的脚本在Ubuntu 10.10的原始版本上成功运行。（Python2.6.6）

所以我手动编译并安装了pyhton2.7（从源代码）。我的剧本不起作用了：Error: ImportError: No module named lxml

我已经返回到python2.6.7（来自源代码），但错误仍在发生。调用正确的python版本（2.6.7）。

注意：错误发生后，我多次删除并重新安装了包python-lxml。错误仍然存在：sudo aptitude install pyhton-lxml

我需要执行某种神奇的脚本来让python找到模块吗？

下面是命令的输出：strace ./RunScriptPython.py（带有python -v）$ strace ./RunScriptPython.sh
