这是因为Linux缺少微软的office

# Linux安装Libreoffice

安装：https://blog.csdn.net/a1275302036/article/details/134806486

离线安装：https://blog.csdn.net/nothing_may/article/details/122175775

首先在官网下载对应的压缩包：libreoffice压缩包下载链接 (opens new window)

解压压缩包（我直接放到opt下解压）

tar -zxvf LibreOffice_7.1.8_Linux_x86-64_rpm.tar.gz

cd到解压的包中的RPMS目录下进行下载

# 下载
yum localinstall *.rpm
# 启动
/opt/libreoffice7.1/program/soffice --headless --accept="  socket,host=127.0.0.1,port=8100;urp;"- -nofirststartwizard &

# 启动报错

# 报错1

/opt/libreoffice7.1/program/soffice.bin: error while loading shared libraries: libSM.so.6: cannot open shared object file: No such file or directory

这是因为缺少了libSM.so.6包

下载libSM.so.6包：libSM.so.6压缩包下载地址 (opens new window)

把包放到系统上直接安装

yum localinstall libSM-1.2.3-1.el8.x86_64.rpm

# 报错2

/opt/libreoffice7.1/program/soffice.bin: error while loading shared libraries: libcairo.so.2: cannot open shared object file: No such file or directory

解决

yum install -y cairo

# 报错3

/opt/libreoffice7.1/program/soffice.bin: error while loading shared libraries: libcups.so.2: cannot open shared object file: No such file or directory

解决

yum install cups-libs
