我是Anaconda的新手。我在Centos 7.3服务器上安装了Anaconda24.4.0Linuxx86_64.sh，安装在终端后（我使用PuTTY作为连接服务器的模拟器）我输入了anaconda-navigator。我收到以下错误消息：
This application failed to start because it could not find or load the
Qt platform plugin "xcb" in "".
Available platform plugins are: minimal, offscreen, xcb.
Reinstalling the application may fix this problem.
Aborted (core dumped)
有关如何克服此问题的任何想法或建议？在我的conda信息和conda列表下面。
