1.cd进入appimage所在的目录

cd your_folder

2.赋予appimage运行权限

chmod +x your_file.appimage

3.运行appimage格式文件

./your_file.appimage

4.可能发现无法运行提示

dlopen(): error loading libfuse.so.2

AppImages require FUSE to run. 
You might still be able to extract the contents of this AppImage 
if you run it with the --appimage-extract option. 
See https://github.com/AppImage/AppImageKit/wiki/FUSE 

5.安装fuse2

sudo pacman -S fuse2

6.再次运行就可以了
7.如果仍出错,就可能是因为下载的appimage不完整或出错或没安装相应依赖
