如何使用 pyuno 调试崩溃的 openoffice

Question

我想使用 openoffice 以编程方式将 docx 转换为 pdf。我知道 unoconv 可以做到这一点，而且 unoconv 确实会为我做到这一点，即使我运行一个单独的侦听器（使用unoconv -l）并调用unoconv -n（这样如果它无法连接到侦听器就会死掉） .因此，我假设我的 openoffice/pyuno 环境是健全的。

但是，当我运行 unoconv 侦听器（或手动调用 openoffice 作为接受器）并尝试使用我自己的 python 代码（从 unoconv 派生，并与另一个 openoffice 库进行交叉检查）连接时，侦听器死了，并且uno 桥死了。

我从监听器得到的错误是：

terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException'

我在python端得到的错误是：

unoconv: RuntimeException during import phase:
Office probably died. Binary URP bridge disposed during call

我真的不知道如何诊断这里的问题。任何有关根本原因或如何诊断的建议将不胜感激。

代码如下：

Answer 1

我不知道这是否是你的情况，但我发现 LogMeIn（在我的机器上运行）也在使用端口 2002。当我在那台机器上尝试 unoconv 时，我得到了同样的错误：Binary URP bridge通话期间处置。 我杀死了 LogMeIn，之后一切正常。

希望这会有所帮助！
