python - 在 Ubuntu 中找不到(但已安装)模块

安装 lxml 模块后,我的脚本在原始版本的 Ubuntu 10.10 上成功运行。 ( python 2.6.6)

所以我已经手动编译并安装了 pyhton2.7(来自源代码)。我的脚本不再有效:

Error: ImportError: No module named lxml

我已经回到python2.6.7(从源代码),但错误不断发生。调用正确的 python 版本 (2.6.7)。

注意:我在错误发生后多次删除并重新安装了软件包python-lxml。错误仍然存​​在:

sudo aptitude install pyhton-lxml

我是否必须执行某种神奇的脚本才能让 python 找到模块?

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

最佳答案

要测试我的诊断(如下)是否正确,您可以尝试运行

/usr/bin/python ./RunScriptPython.py

(应该可以。)


请注意您发布的输出中的这一点:

import site # precompiled from /usr/local/lib/python2.6/site.pyc

导入正在查找/usr/local/lib/python2.6。这不是 Ubuntu 系统默认的 python 版本。这是本地安装。

当您安装 python-lxml 包时,它安装在/usr/lib/python2.6/中,并且可以使用/usr/bin 中的 Ubuntu 系统默认版本的 python 访问,而不是/usr/您似乎正在运行 python 的本地/bin 版本。

除非出于某种原因需要/usr/local 版本的 python,最简单的解决方案是卸载它并使用/usr/bin 版本的 python。
