我在腾讯云的uduntu服务器上,按照文档中教程安成功vnpy后,运行example/vn_trade/目录下的 run.py, 出现如下错误:
qt.qpa.xcb: could not connect to display
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, webgl, xcb.
请问各位大神,咋解决啊!困扰好几天了
