ros - 遵循 ROS 教程时出现此错误

问题描述

我对 ROS 比较陌生，并且正在学习教程。当我输入命令时，点击链接http://wiki.ros.org/ROS/Tutorials/UnderstandingTopicsrosrun rqt_plot rqt_plot。我收到以下错误。这是什么意思？

    PluginManager._discover() force discovery of plugins
RospkgPluginProvider._find_plugins() crawling for plugins of type 'qt_gui'
Could not import "pyside" bindings of qt_gui_cpp library - so C++ plugins will not be available:
