我正在尝试在 WSL2 上运行一个简单的 PySide6 应用程序

$ python3 -m venv venv
$ . ./venv/bin/activate
$ pip install PySide6
$ sudo apt install libopengl0 libegl1

我的代码：

import sys
from PySide6.QtCore import Qt
from PySide6.QtWidgets import QApplication, QLabel
                                                     
if __name__ == "__main__":
    app = QApplication(sys.argv)
    label = QLabel("Hello World", alignment=Qt.AlignCenter)
    label.show()
    sys.exit(app.exec_())

当我运行时，我得到了错误

$ export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2}'):0\n
$ python main.py
qt.qpa.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: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

[1]    2557 abort      python main.py

是否可以使用 WSL2 运行 PySide 应用程序？如果是，如何？

1、X服务器https://techcommunity.microsoft.com/t5/windows-dev-appconsult/running-wsl-gui-apps-on-windows-10/ba-p/1493242

i) 安装https://sourceforge.net/projects/vcxsrv/

ii)export DISPLAY="`grep nameserver /etc/resolv.conf | sed 's/nameserver //'`:0"

iii) 运行xev测试图像

iv) 在文件末尾包含命令 ii /etc/bash.bashrc：

2、 sudo apt install pyside2-tools libopengl-dev

3，运行python3 xxx.py 它工作，但仍然有一些问题。输出：

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-dev'
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
