kunpeng的aarch64架构cpu、openeuler系统、昇腾服务器适配文档转换功能（doc转docx、ppt转pptx）

一、安装flatpak

sudo yum install flatpak  
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

二、安装libreoffice

flatpak install flathub org.libreoffice.LibreOffice

三、使用

对于使用 flatpak 安装的 LibreOffice,不需要手动启动或设置任何环境变量。flatpak 提供了一个沙箱化的运行环境,确保应用程序可以正常运行。
flatpak 应用程序的可执行文件通常位于类似

/var/lib/flatpak/app/org.libreoffice.LibreOffice/aarch64/stable/active/export/bin/org.libreoffice.LibreOffice

只要在代码中正确指定了这个完整路径,就可以直接运行和调用 LibreOffice,而无需进行任何其他设置。

四、示例代码-doc

import tqdm
import subprocess
import os
from dotenv import load_dotenv
from docx.table import _Cell, Table
from docx.oxml.table import CT_Tbl
from docx.oxml.text.paragraph import CT_P
