在Plone中安装文档查看器

Question

我一直在试图在Plone上安装document.viewer，它允许我查看内嵌的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文件给出以下错误，我的操作系统是Fedora。

Traceback (most recent call last): 
    File "/usr/local/Plone/buildout-cache/eggs/collective.documentviewer-2.2-py2.7.egg/collective/documentviewer/convert.py", line 530, in __call__ 
    pages = self.run_conversion() 
    File "/usr/local/Plone/buildout-cache/eggs/collective.documentviewer-2.2-py2.7.egg/collective/documentviewer/convert.py", line 379, in run_conversion 
    return docsplit.convert(self.storage_dir, **args) 
    File "/usr/local/Plone/buildout-cache/eggs/collective.documentviewer-2.2-py2.7.egg/collective/documentviewer/convert.py", line 285, in convert

    File "/usr/local/Plone/buildout-cache/eggs/collective.documentviewer-2.2-py2.7.egg/collective/documentviewer/convert.py", line 256, in convert_to_pdf

    File "/usr/local/Plone/buildout-cache/eggs/collective.documentviewer-2.2-py2.7.egg/collective/documentviewer/convert.py", line 118, in _run_command 
    raise Exception(error) 
Exception: Command

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作为一个独立的管理权限来安装。我该如何解决这个问题？

你是否安装了所有的依赖关系，如https://pypi.python.org/pypi/collective.documentviewer/#install-requirements？
