这个是什么原因啊，我换了一台服务器还是这样

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, xcb.

Start with the reported Qt platform-plugin error and compare the runtime environment on the affected Linux servers, including whether the xcb dependencies are available. Done means identifying a reproducible cause and documenting a verified resolution; the issue does not name a source file or test to change.
