Ubuntu22.04下pythonOCC运行报错：缺失Qt平台插件wayland

在Ubuntu 22.04机器的Anaconda虚拟环境（Python3.9）中已成功安装PythonOCC 7.7.0版本。运行测试示例代码时，先出现无可视化后端相关报错，通过conda安装PySide2后，报错变为找不到Qt平台插件"wayland"。尝试安装wxpython、PyQt、qtwayland5并设置环境变量等方法均未解决问题，寻求可行解决方案。

测试代码 #

from OCC.Display.SimpleGui import init_display
from OCC.Core.BRepPrimAPI import BRepPrimAPI_MakeBox
display, start_display, add_menu, add_function_to_menu = init_display()
my_box = BRepPrimAPI_MakeBox(10., 20., 30.).Shape()
display.DisplayShape(my_box, update=True)
start_display()

报错信息 #
