我一直在尝试在 Plone 上安装 document.viewer，这将允许我内联查看 pdf 文档，到目前为止，我能够转换 pdf 文件并查看它们，但是当我尝试转换 .doc .ppt 文件时，它给出了以下错误，我的操作系统是Fedora。
Traceback (most recent call last):

and output:
Error: Could not find or load main class .usr.lib.libreoffice
请注意，我已经安装了 openoffice，并且在 usr/lib 文件夹中有一个名为 libreoffice 的文件夹。Plone 作为具有管理权限的独立设备安装。我该如何解决这个问题？
