Linux Debian 10-qt.qpa.plugin:无法加载qt平台插件"；xcb"；在&引用；即使它被发现了

运行rstudio命令时，出现以下错误：

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, xcb.

Aborted (core dumped)

我已经查看了所有其他回复，并“解决”了有关此问题的问题，但他们没有为我解决问题，我也不知道如何为我的特定设备单独解决此问题

有人能告诉我如何在不使用复杂语言的情况下解决这个问题吗？ 我不知道任何访问东西的命令，因此尝试使用在线答案非常困难

这是我运行rstudio时的完整输出：

谁能告诉我重新安装插件所需的命令？我没有看到任何人在任何地方发布该消息。

根据错误消息

无法连接到display

是否设置了display变量？运行

echo$DISPLAY

命令。您看到设置此变量的说明了吗？@SameerNaik运行此命令会为我返回：0
