解决Ubuntu安装QT：From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.

【完整报错】From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: wayland, minimal, minimalegl, vkkhrdisplay, offscreen, vnc, xcb, wayland-egl, linuxfb, eglfs.

这是我参考一篇博主的解决办法：https://blog.youkuaiyun.com/m0_64405299/article/details/137184349

解决办法：

1、终端输入命令先更新，确保自己已经安装下面内容：

sudo apt-get update
sudo apt-get install gcc #安装gcc编译器
sudo apt-get install g++ #安装g++编译器
sudo apt-get install make #安装make构建套件
sudo apt-get install libgl1-mesa-dev #安装OpenGL核心库

2、需要安装xcb-cursor0 库

sudo apt-get install libxcb-cursor0

3、最后重新点击QT就能成功启动了
