Could Not Find Or Load The Qt Platform Plugin Install QT Even
Finally, trying the "rqt" command from the same tutorial yields: RosPluginProvider._parse_plugin_xml() plugin file "C:\dev\ros2_eloquent\share\qt_gui_cpp/plugin.xml" in package "qt_gui_cpp" not foundRosPluginProvider._parse_plugin_xml() plugin file "C:\dev\ros2_eloquent\share\rqt_gui_cpp/plugin.xml" in package "rqt_gui_cpp" not foundRosPluginProvider._parse_plugin_xml() plugin file "C:\dev\ros2_eloquent\share\qt_gui_cpp/plugin.xml" in package "qt_gui_cpp" not foundI have extra checked the PATH variables from the guide and also added "C:\Python37\Lib\site-packages\PyQt5\Qt\plugins\platforms", but no success.Any solution to this? Do I need to install QT even though it's not in the guide? Thankful for answers. Reinstalling the application may fix this problem.Found a thread with the same problem, but this solution seems to fix the problem when installing from source and hence installing QT, which is not needed for the binary install?. And using the turtlesim command: C:\WINDOWS\system32>ros2 run turtlesim turtlesim_nodeThis application failed to start because it could not find or load the Qt platform plugin "windows" in "".
