3、问题分析
通过阅读官方更新内容得知，KKFileView在4.0.0版本之后，将底层集成 OpenOffice 替换为了 LibreOffice，而 OpenOffice 本身在linux的安装盘中都会携带，不需要自行安装。
而此次更新将底层替换成了 LibreOffice，由于 linux 中没有，自然就会出现报错。kkFileView v4.0.0 发布，文件文档在线预览解决方案 - OSCHINA - 中文开源技术交流社区
https://www.oschina.net/news/149206/kkfileview-4-0-released
4、解决方法
4.1、下载
既然没有 LibreOffice，那么下载一个即可，前往官方下载：Download LibreOffice | LibreOffice - Free Office Suite - Based on OpenOffice - Compatible with Microsofthttps://www.libreoffice.org/download/download-libreoffice/
选择下载 “LibreOffice_7.6.7_Linux_x86-64_rpm.tar.gz”
4.2、安装步骤
- 上传：首先将安装包上传到 linux 服务器
- 删除：在安装之前，先删除已经安装的 LibreOffice： yum remove libreoffice*
- 解压： tar -xvf LibreOffice_7.6.7_Linux_x86-64_rpm.tar.gz
- 安装： cd LibreOffice_7.6.7_Linux_x86-64_rpm/RPMS yum localinstall *.rpm
完成以上步骤后，重新启动KKFileView就可以看到运行成功了！
