qt.qpa.plugin: Could not load the Qt platform plugin “xcb“ in

兄弟们���看是不是这个错：

QObject::moveToThread: Current thread (0xe5205f0) is not the object's thread (0xa14d0f0).Cannot move to target thread (0xe5205f0)qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/xxx/python3.8/site-packages/cv2/qt/plugins" 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: xcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl.

VScode 80年不出个错，今儿冒出来这个，我也不知道是mmdet配置问题，还是opencv-python的问题，还是VScode的问题hhhh

把QT的flag打开，我们才能看到报错的详细信息

export QT_DEBUG_PLUGINS=1

注意，这个执行后，该环境变量只在当前终端有效，关了这个终端就失效了，当然你也可以写到.bashrc里

然后就整出一个超级长的报错：

与这哥们报的错误差不多

这位大哥这样做的

当然你也可以在环境变量中添加：

export DISPLAY=:0

launch.json 中这样添加

解决是解决了，但是给我整出来一个

Invalid MIT-MAGIC-COOKIE-1 Key(环境变量名字)

暂时不影响
